Description

分析用容器、それを用いたターゲット分析用具およびターゲット分析方法Analysis container, target analysis tool and target analysis method using the same
 本発明は、分析用容器、それを用いたターゲット分析用具およびターゲット分析方法に関する。 The present invention relates to an analysis container, a target analysis tool using the same, and a target analysis method.
 ターゲットの分析においては、一般的に、前記ターゲットに対する結合性を有する結合物質を使用し、前記ターゲットと前記結合物質との結合体を形成させ、これを直接的または間接的に検出することによって、ターゲットの有無または量を分析できる(特許文献1、特許文献2)。 In target analysis, generally, a binding substance having binding properties to the target is used, and a conjugate of the target and the binding substance is formed, and this is detected directly or indirectly, The presence / absence or amount of the target can be analyzed (Patent Document 1, Patent Document 2).
 しかし、このように結合物質を使用した分析方法においては、前記ターゲットと結合した結合物質と前記ターゲットに未結合の結合物質との分離が必要とされているため、一つの分析用具内で一連の処理を行い、ターゲットを検出することが困難である。 However, in the analysis method using the binding substance in this way, it is necessary to separate the binding substance bound to the target and the binding substance not bound to the target. It is difficult to perform processing and detect a target.

 前記ターゲットと結合した結合物質と前記ターゲットに未結合の結合物質との分離を行なうための分析用具として、有底筒状の分析用容器内に、前記ターゲットと結合した結合物質と前記ターゲットに未結合の結合物質とを分離可能な隔壁を配置した分析用容器が考えられた。前記分析用容器では、前記隔壁の開口側の室において、前記ターゲットと前記結合物質との結合体を形成させた後、前記ターゲットと前記結合物質との混合物を、前記隔壁を通過させて底部側の室に導入することにより、前記ターゲットと結合した結合物質と前記ターゲットに未結合の結合物質とを分離できる。しかしながら、前記分析用容器では、前記隔壁を介した前記開口側の室から前記底部側の室への前記ターゲットと前記結合物質との混合物の移動が実質的に生じないという問題があった。 As an analysis tool for separating the binding substance bound to the target and the binding substance unbound to the target, the binding substance bound to the target and the target not bound to the target are placed in a bottomed cylindrical analysis container. An analytical container in which a partition wall capable of separating the binding substance of the binding was arranged was considered. In the analysis container, in the chamber on the opening side of the partition wall, a combined body of the target and the binding substance is formed, and then the mixture of the target and the binding substance is passed through the partition wall to be on the bottom side. By introducing into this chamber, the binding substance bound to the target and the binding substance not bound to the target can be separated. However, the analysis container has a problem that the mixture of the target and the binding substance does not substantially move from the opening-side chamber to the bottom-side chamber via the partition wall.
 また、前記分析用容器において、前記底部側の室に通気用の貫通孔を設けた場合、前記開口側の室において、前記ターゲットと前記結合物質との形成体を形成する前に、前記ターゲットと前記結合物質との混合物が、前記隔壁を通過し、前記底部側の室に導入されることがある。このため、十分な分析精度が得られない場合があるという問題があった。 Further, in the analysis container, when a through-hole for ventilation is provided in the bottom side chamber, the target and the binding substance are formed in the chamber on the opening side before the formation body of the target and the binding substance is formed. The mixture with the binding substance may pass through the partition and be introduced into the bottom chamber. For this reason, there is a problem that sufficient analysis accuracy may not be obtained.
 そこで、本発明は、分析用容器内の通液を制御可能な分析用容器、それを用いたターゲット分析用具およびターゲット分析方法を提供することを目的とする。 Therefore, an object of the present invention is to provide an analysis container capable of controlling the flow of liquid in the analysis container, a target analysis tool and a target analysis method using the same.

<Container for analysis>
As described above, the analysis container of the present invention includes the first chamber, the second chamber, and the third chamber, and the first chamber, the second chamber, and the third chamber are sequentially arranged in this order. And having a first partition between the first chamber and the second chamber, and having a second partition between the second chamber and the third chamber, A sample holding tool can be inserted from the outside into the inside, and the first partition is a partition that is broken by bringing the tip of the sample holding tool inserted into the first chamber into contact with the second partition. The partition wall is a porous partition wall, the third chamber includes one or more through holes, and an openable and closable closing member is disposed in the through hole so as to cover the through hole. By opening the hole from the closing member, liquid can be passed from the second chamber to the third chamber. In the analysis container according to the present invention, the third chamber includes one or more through holes, and an opening / closing closing member is disposed in the through hole so as to cover the through hole. It is a feature that the liquid can be passed from the second chamber to the third chamber by opening from the closing member, and other configurations and conditions are not particularly limited. The blocking member can be said to be a member capable of controlling the opening and closing of the through hole, for example.
 本発明の分析用容器において、例えば、前記第2室に液体を導入すると、前記液体は、前記第2室と前記第3室との間の前記第2隔壁を通過し、前記第3室へ移動しようとする。しかしながら、この際に、前記閉塞部材が前記貫通孔を覆う状態で配置されていると、例えば、前記第3室の空気は、前記第3室から移動できない。このため、前記空気と置換されることにより前記第3室に導入される前記液体は、例えば、前記第2室から前記第3室に実質的に移動しない。他方、前記閉塞部材が除去され、前記貫通孔が前記閉塞部材から開放されると、例えば、前記第3室の空気は、前記貫通孔を介して、前記分析用容器外に移動可能となる、すなわち、前記第3室は、例えば、通気可能となる。このため、前記液体は、例えば、前記第2室から前記第3室に移動可能となり、前記第2室から前記第3室に移動する。したがって、本発明の分析用容器によれば、前記閉塞部材により前記貫通孔の開閉を制御することにより、前記第2室から前記第3室への通液を簡便に制御できる。 In the analysis container of the present invention, for example, when a liquid is introduced into the second chamber, the liquid passes through the second partition wall between the second chamber and the third chamber, and enters the third chamber. Try to move. However, at this time, if the closing member is disposed in a state of covering the through hole, for example, the air in the third chamber cannot move from the third chamber. For this reason, the liquid introduced into the third chamber by being replaced with the air does not substantially move from the second chamber to the third chamber, for example. On the other hand, when the blocking member is removed and the through hole is opened from the blocking member, for example, the air in the third chamber can be moved out of the analysis container via the through hole. That is, the third chamber can be vented, for example. For this reason, for example, the liquid can move from the second chamber to the third chamber, and moves from the second chamber to the third chamber. Therefore, according to the analytical container of the present invention, liquid flow from the second chamber to the third chamber can be easily controlled by controlling the opening and closing of the through hole by the closing member.
 以下、本発明の分析用容器について、図面を参照して、例をあげて詳細に説明する。ただし、本発明は、以下の例に限定および制限されない。また、図面においては、説明の便宜上、各部の構造は適宜簡略化して示す場合があり、各部の寸法比等は、実際とは異なり、模式的に示す場合がある。各実施形態は、特に言及しない限り、互いに組合せ可能である。 Hereinafter, the analysis container of the present invention will be described in detail with reference to the drawings with examples.

Moreover, the analysis method of Embodiment 4A uses the target analysis tool of Embodiment 4A,
After a sample holding tool holding a sample is inserted into the first chamber of the target analysis tool, the sample holding tool is brought into contact with the first partition between the first chamber and the second chamber, and the sample is placed in the second chamber. And introducing the first reagent,
In the second chamber, the sample, the first reagent, and the second reagent are brought into contact with each other, and the target in the sample and the labeled first binding substance that is the second reagent are bound to each other. And binding the labeled first binding substance unbound to the target to the immobilized second binding substance that is the first reagent,

 本実施形態によれば、まず、前記第1室において、例えば、試料中のターゲットと前記第1試薬である前記固定化第2結合物質とが混合する。そして、前記第1室における前記試料と前記第1試薬との混合物が、前記第2室に導入されると、前記第2室では、前記試料中のターゲットと前記第2試薬である前記標識化第1結合物質とが結合し、且つ、未結合の前記標識化第1結合物質と前記第1試薬である前記固定化第2結合物質とが結合する。そして、前記第2室と前記第3室との間の第2隔壁は、前記固定化第2結合物質が通過できず、前記標識化第1結合物質を含む第1結合体が通過できる前記多孔性隔壁であるため、前記固定化第2結合物質は、前記隔壁を通過せずに前記第2室に残る。つまり、前記固定化第2結合物質に結合した前記標識化第1結合物質は、前記第3室に移動することなく前記第2室に残る。他方、前記固定化第2結合物質に未結合の遊離した前記標識化第1結合物質、すなわち前記第1結合体を形成している前記標識化第1結合物質は、前記隔壁を通過して前記第3室に導入される。本実施形態の分析用具における前記標識化第1結合物質は、例えば、既知量とすることができるため、前記固定化第2結合物質に未結合の前記標識化第1結合物質の量は、前記試料中のターゲット量と間接的に対応することになる。このため、前記第3室に導入された前記未結合の標識化第1結合物質を検出することによって、間接的に、前記試料中のターゲットの有無または量を分析することができる。 According to this embodiment, first, in the first chamber, for example, the target in the sample and the immobilized second binding substance that is the first reagent are mixed. When the mixture of the sample and the first reagent in the first chamber is introduced into the second chamber, the labeling that is the target in the sample and the second reagent is performed in the second chamber. The first binding substance binds to the unbound labeled first binding substance and the immobilized second binding substance as the first reagent. The second partition between the second chamber and the third chamber cannot pass through the immobilized second binding substance, and can pass through the first conjugate containing the labeled first binding substance. Since the barrier rib is an insulating partition, the immobilized second binding substance remains in the second chamber without passing through the partition. That is, the labeled first binding substance bound to the immobilized second binding substance remains in the second chamber without moving to the third chamber. On the other hand, the labeled first binding substance released unbound to the immobilized second binding substance, that is, the labeled first binding substance forming the first conjugate passes through the partition wall and passes through the partition wall. Introduced into the third chamber. Since the labeled first binding substance in the analysis tool of the present embodiment can be, for example, a known amount, the amount of the labeled first binding substance unbound to the immobilized second binding substance is This indirectly corresponds to the target amount in the sample. Therefore, the presence or amount of the target in the sample can be indirectly analyzed by detecting the unbound labeled first binding substance introduced into the third chamber.
 以下、前記(1)の組合せの分析用具およびそれを用いた(A)の分析方法について、分析用容器として、前記実施形態1の分析用容器を使用し、前記第1結合物質としてアプタマーを使用する形態を、例にあげて説明する。 Hereinafter, for the analysis tool of the combination of (1) and the analysis method of (A) using the same, the analysis container of Embodiment 1 is used as the analysis container, and the aptamer is used as the first binding substance The form to be described will be described by way of example.

When the labeling substance is the catalyst nucleic acid molecule, the catalyst nucleic acid molecule may serve as both the labeling substance and the second binding substance.

The solvent is not particularly limited, and examples thereof include water, physiological saline, and buffer solution. The sample may be, for example, a sample including the target, a sample not including the target, or a sample unknown whether the target is included.
 本実施形態では、前述のように、前記第1結合物質としてアプタマー、前記第2結合物質として相補性核酸分子を使用できることから、例えば、熱安定性であり、保存がより容易である。また、前記標識物質として、例えば、ルシフェラーゼ、アルカリフォスファターゼ、ペルオキシダーゼ等の酵素を使用できることから、例えば、感度よくターゲットを分析できる。 In the present embodiment, as described above, since aptamers can be used as the first binding substance and complementary nucleic acid molecules can be used as the second binding substance, for example, it is heat-stable and is easier to store. Moreover, since an enzyme such as luciferase, alkaline phosphatase or peroxidase can be used as the labeling substance, for example, the target can be analyzed with high sensitivity.

When the second chamber includes the adsorption carrier, proteins, lipids, and the like are adsorbed on the adsorption carrier in the second chamber. For this reason, for example, the introduction of proteins, lipids, etc. that affect the catalytic function of the catalytic nucleic acid molecule into the third chamber is prevented, and the unbound labeled first binding substance in the third chamber is prevented.

In FIG. 4, the same parts as those in FIG. The analysis tool 4 has a first chamber 11, a second chamber 12, and a third chamber 13, and an immobilized complementary strand 19 in which a complementary strand 191 for the aptamer 181 is immobilized on a bead 192 is contained in the first chamber 11. In the second chamber 12, a labeled aptamer 18 obtained by adding an enzyme 182 to the aptamer 181 is disposed. A first partition 111 is provided between the first chamber 11 and the second chamber 12, and a porous second partition 121 is provided between the second chamber 12 and the third chamber 13. The third chamber 13 has a through hole 14, and a sealing member 151, which is the closing member, is disposed on the outer surface of the third chamber 13 so as to cover the through hole 14. The seal member 151 can be peeled off from the outer surface of the third chamber 13. The sample holding tool 20 includes a rod-shaped gripping part 201 and a sample holding part 202, and the holding part 202 is disposed at the tip of the gripping part 201. The sample holding tool 20 collects a sample with the holding unit 202. For example, the target 21 in the sample adheres to the holding unit 202.
 つぎに、図4の分析用具4を使用した分析方法について、図5を用いて説明する。図5は、分析用具4の使用方法を示す概略図である。 Next, an analysis method using the analysis tool 4 of FIG. 4 will be described with reference to FIG. FIG. 5 is a schematic view showing how to use the analytical tool 4.
 まず、分析用具4の第1室11に、保持部202に試料を保持させた試料保持用具20を挿入し、第1室11において、試料中のターゲット21と固定化相補鎖19とを混合させる。前記両者の混合の処理条件は、特に制限されず、温度が、例えば、4~37℃、時間が、例えば、10秒~30分である。前記両者の混合は、例えば、液体溶媒中で行うことが好ましく、前記液体溶媒は、例えば、水、緩衝液、生理食塩水、これらの混合液等の水性溶媒があげられる。 First, the sample holding tool 20 in which the sample is held in the holding portion 202 is inserted into the first chamber 11 of the analysis tool 4, and the target 21 in the sample and the immobilized complementary strand 19 are mixed in the first chamber 11. . The processing conditions for mixing the two are not particularly limited, and the temperature is, for example, 4 to 37 ° C., and the time is, for example, 10 seconds to 30 minutes. The mixing of the two is preferably performed, for example, in a liquid solvent, and examples of the liquid solvent include water, a buffer solution, physiological saline, and an aqueous solvent such as a mixed solution thereof.
 つぎに、試料保持用具20により、第1隔壁111を破壊し、第1室11内の内容物を第2室12に導入する。そして、前記内容物中のターゲット21を標識化アプタマー18に結合させ、また、標識化アプタマー18のうち、ターゲット21と未結合である標識化アプタマー18を、固定化相補鎖19に結合させる。また、前記両者の結合処理中、第3室13の外表面に、シール部材151が、貫通孔14を覆う状態で配置されている。前記両者の結合の処理条件は、特に制限されず、温度が、例えば、4~37℃、時間が、例えば、10秒~30分である。前記両者の結合は、例えば、前記液体溶媒中で行うことが好ましい。 Next, the first partition 111 is broken by the sample holding tool 20, and the contents in the first chamber 11 are introduced into the second chamber 12. Then, the target 21 in the contents is bound to the labeled aptamer 18, and among the labeled aptamers 18, the labeled aptamer 18 that is not bound to the target 21 is bound to the immobilized complementary strand 19. Further, a sealing member 151 is disposed on the outer surface of the third chamber 13 so as to cover the through hole 14 during the coupling process of the both. The treatment conditions for the combination of the two are not particularly limited, and the temperature is, for example, 4 to 37 ° C., and the time is, for example, 10 seconds to 30 minutes. The bonding between the two is preferably performed, for example, in the liquid solvent.
 さらに、前記結合処理中または処理後に、貫通孔14からシール部材151が剥離されると、第2室12から第3室13への通液が可能となる。第2隔壁121は、固定化相補鎖19を通過せず、標識化アプタマー18とターゲット21との第1結合体を通過する多孔性隔壁であるため、標識化アプタマー18のうち、固定化相補鎖19に未結合のもののみが、第2隔壁121を通過して、第3室13に導入される。そして、第3室13において、固定化相補鎖19に未結合の標識化アプタマー18について、酵素182の触媒機能を測定することにより、間接的に、試料中のターゲットを分析できる。酵素182の触媒機能の測定は、酵素182の種類に応じて適宜決定できる。 Furthermore, when the sealing member 151 is peeled from the through hole 14 during or after the bonding process, the liquid can be passed from the second chamber 12 to the third chamber 13. Since the second partition 121 is a porous partition that does not pass through the immobilized complementary strand 19 and passes through the first conjugate of the labeled aptamer 18 and the target 21, the immobilized complementary strand of the labeled aptamer 18. Only the unbonded material 19 passes through the second partition 121 and is introduced into the third chamber 13. Then, in the third chamber 13, the target in the sample can be indirectly analyzed by measuring the catalytic function of the enzyme 182 for the labeled aptamer 18 that is not bound to the immobilized complementary strand 19. The measurement of the catalytic function of the enzyme 182 can be appropriately determined according to the type of the enzyme 182.

前記第3室は、前記標識化第1結合物質が検出される検出部であり、
前記第2隔壁は、前記固定化第2結合物質が通過できず、試料中のターゲットと前記第1試薬である前記標識化第1結合物質とが結合した第1結合体が通過できる多孔性隔壁である。
The analysis tool of Embodiment 4B includes the analysis container of the present invention, a first reagent, and a second reagent,
The first chamber includes, as the first reagent, a labeled first binding substance in which a labeling substance is bound to a first binding substance that binds to a target;

The third chamber is a detection unit for detecting the labeled first binding substance,
The second partition wall is a porous partition wall through which the immobilized second binding substance cannot pass, but through which the first combined body in which the target in the sample and the labeled first binding substance as the first reagent are bound can pass through. It is.
 また、実施形態4Bの分析方法は、前記実施形態4Bのターゲット分析用具を使用し、
前記ターゲット分析用具の前記第1室に、試料を保持した試料保持用具を挿入する工程、
前記第1室において、前記第1試薬と前記試料とを接触させ、前記試料中のターゲットと前記第1試薬である前記標識化第1結合物質とが結合した第1結合体を形成させる工程、
前記第2室において、前記第2試薬と、前記試料と前記第1試薬との混合物とを接触させ、前記混合物中の前記ターゲットに未結合の前記標識化第1結合物質を前記第2試薬である前記固定化第2結合物質に結合させる工程、
前記第1結合体を、前記第2室と前記第3室との間の第2隔壁を通過させ、前記第3室に導入する工程、および、
前記第3室において、前記第1結合体における前記標識化第1結合物質を検出する工程を含む。
Moreover, the analysis method of Embodiment 4B uses the target analysis tool of Embodiment 4B,
Inserting a sample holding tool holding a sample into the first chamber of the target analysis tool;
Contacting the first reagent with the sample in the first chamber to form a first conjugate in which the target in the sample is bound to the labeled first binding substance as the first reagent;
In the second chamber, the second reagent is brought into contact with the mixture of the sample and the first reagent, and the labeled first binding substance unbound to the target in the mixture is used as the second reagent. Binding to the immobilized second binding substance,
Introducing the first combined body into the third chamber through a second partition between the second chamber and the third chamber; and
In the third chamber, the method includes detecting the labeled first binding substance in the first conjugate.
 本実施形態によれば、まず、前記第1室において、試料中のターゲットと前記第1試薬である前記標識化第1結合物質とが結合する。そして、前記第1室における前記試料と前記第1試薬との混合物が、前記第2室に導入されると、前記第2室では、前記標識化第1結合物質のうち、前記ターゲットに未結合の前記標識化第1結合物質に、前記固定化第2結合物質が結合する。そして、前記第2室と前記第3室との間の第2隔壁は、前記固定化第2結合物質が通過できず、前記第1標識化結合物質を含む前記第1結合体が通過できる前記多孔性隔壁であるため、前記固定化第2結合物質は、前記隔壁を通過せずに前記第2室に残る。つまり、前記固定化第2結合物質に結合した前記標識化第1結合物質は、前記第3室に移動することなく前記第2室に残る。他方、前記固定化第2結合物質に未結合の遊離した前記標識化第1結合物質、すなわち前記第1結合体を形成している前記標識化第1結合物質は、前記隔壁を通過して前記第3室に導入される。本実施形態の分析用具における前記標識化第1結合物質は、例えば、既知量とすることができるため、前記固定化第2結合物質に未結合の前記標識化第1結合物質の量は、前記試料中のターゲット量と間接的に対応することになる。このため、前記第3室に導入された前記未結合の標識化第1結合物質を検出することによって、間接的に、前記試料中のターゲットの有無または量を分析することができる。 According to the present embodiment, first, in the first chamber, the target in the sample and the labeled first binding substance as the first reagent are bound. When the mixture of the sample and the first reagent in the first chamber is introduced into the second chamber, the second chamber is not bound to the target among the labeled first binding substances. The immobilized second binding substance binds to the labeled first binding substance. The second partition between the second chamber and the third chamber cannot pass through the immobilized second binding substance, and can pass through the first conjugate containing the first labeled binding substance. Since it is a porous partition wall, the immobilized second binding substance remains in the second chamber without passing through the partition wall. That is, the labeled first binding substance bound to the immobilized second binding substance remains in the second chamber without moving to the third chamber. On the other hand, the labeled first binding substance released unbound to the immobilized second binding substance, that is, the labeled first binding substance forming the first conjugate passes through the partition wall and passes through the partition wall. Introduced into the third chamber. Since the labeled first binding substance in the analysis tool of the present embodiment can be, for example, a known amount, the amount of the labeled first binding substance unbound to the immobilized second binding substance is This indirectly corresponds to the target amount in the sample. Therefore, the presence or amount of the target in the sample can be indirectly analyzed by detecting the unbound labeled first binding substance introduced into the third chamber.
 以下、前記(2)の組合せの分析用具およびそれを用いた(B)の分析方法について、分析用容器として、前記実施形態1の分析用容器を使用し、前記第1結合物質としてアプタマーを使用する形態を、例にあげて説明する。実施形態4Bは、例えば、前記実施形態1~3および4A等の説明を援用できる。 Hereinafter, for the analysis tool of the combination (2) and the analysis method (B) using the same, the analysis container of the first embodiment is used as the analysis container, and the aptamer is used as the first binding substance. The form to be described will be described by way of example. For the embodiment 4B, for example, the description of the embodiments 1 to 3 and 4A can be cited.

 本実施形態では、前述のように、前記第1結合物質としてアプタマー、前記第2結合物質として相補性核酸分子を使用できることから、例えば、熱安定性であり、保存がより容易である。また、前記標識物質として、例えば、ルシフェラーゼ、アルカリフォスファターゼ、ペルオキシダーゼ等の酵素を使用できることから、例えば、感度よくターゲットを分析できる。 In the present embodiment, as described above, since aptamers can be used as the first binding substance and complementary nucleic acid molecules can be used as the second binding substance, for example, it is heat-stable and is easier to store. Moreover, since an enzyme such as luciferase, alkaline phosphatase or peroxidase can be used as the labeling substance, for example, the target can be analyzed with high sensitivity.
 本実施形態において、前記第1隔壁は、例えば、前記第1室に挿入された前記試料保持用具の先端を接触させることにより破壊される隔壁でもよいし、前記第1室の内容物を前記第2室に通過できる多孔性隔壁でもよい。前者の場合、破壊により、例えば、前記第1室の内容物を前記第2室に移動することができ、後者の場合、前記多孔性隔壁を通じて、前記第1室の内容物を前記第2室に移動することができる。前者の場合、前述のような破壊可能な部材が使用できる。後者の場合、例えば、前記第1室の内容物が通過可能な孔を有する膜が使用できる。前記第2室と前記第3室との間の前記第2隔壁は、前記実施形態4Aと同様である。 In this embodiment, the first partition may be, for example, a partition that is destroyed by bringing the tip of the sample holding tool inserted into the first chamber into contact, or the contents of the first chamber may be the first partition. It may be a porous partition wall that can pass through two chambers. In the former case, for example, the contents of the first chamber can be moved to the second chamber by destruction, and in the latter case, the contents of the first chamber can be transferred to the second chamber through the porous partition wall. Can be moved to. In the former case, a breakable member as described above can be used. In the latter case, for example, a membrane having holes through which the contents of the first chamber can pass can be used.

 図6は、前記実施形態4Bの分析用具の概略を示す図面である。図6において、図4と同一箇所には同一符号を付している。分析用具5は、第1室11には、アプタマー181に酵素182が付加した標識化アプタマー18が配置され、第2室12には、アプタマー181に対する相補鎖191がビーズ192に固定化された固定化相補鎖19が配置されている。この点を除き、本実施形態の分析用具5は、前記実施形態4Aの分析用具4と同様の構成を有し、その説明を援用できる。 FIG. 6 is a diagram showing an outline of the analysis tool of the embodiment 4B. In FIG. 6, the same parts as those in FIG. In the analysis tool 5, a labeled aptamer 18 in which an enzyme 182 is added to an aptamer 181 is arranged in the first chamber 11, and a complementary strand 191 for the aptamer 181 is immobilized in the beads 192 in the second chamber 12. A complementary strand 19 is arranged. Except for this point, the analysis tool 5 of this embodiment has the same configuration as the analysis tool 4 of Embodiment 4A, and the description thereof can be used.
 つぎに、図6の分析用具5を使用した分析方法について、図7を用いて説明する。図7は、分析用具5の使用方法を示す概略図である。 Next, an analysis method using the analysis tool 5 of FIG. 6 will be described with reference to FIG. FIG. 7 is a schematic view showing how to use the analytical tool 5.
 まず、分析用具5の第1室11に、保持部202に試料を保持させた試料保持用具20を挿入し、第1室11において、試料中のターゲット21を標識化アプタマー18のアプタマー181に結合させる。前記両者の結合の処理条件は、特に制限されず、温度が、例えば、4~37℃、時間が、例えば、10秒~30分である。前記両者の結合は、例えば、液体溶媒中で行うことが好ましく、前記液体溶媒は、例えば、水、緩衝液、生理食塩水、これらの混合液等の水性溶媒があげられる。 First, the sample holding tool 20 in which the sample is held in the holding unit 202 is inserted into the first chamber 11 of the analysis tool 5, and the target 21 in the sample is bound to the aptamer 181 of the labeled aptamer 18 in the first chamber 11. Let The treatment conditions for the combination of the two are not particularly limited, and the temperature is, for example, 4 to 37 ° C., and the time is, for example, 10 seconds to 30 minutes. The combination of the two is preferably performed in, for example, a liquid solvent, and examples of the liquid solvent include aqueous solvents such as water, buffer solution, physiological saline, and a mixed solution thereof.
 つぎに、試料保持用具20により、第1隔壁111を破壊し、第1室11内の内容物を第2室12に導入する。そして、標識化アプタマー18のうち、ターゲット21と未結合である標識化アプタマー18を、固定化相補鎖19に結合させる。また、前記両者の結合処理中、第3室13の外表面に、シール部材151が、貫通孔14を覆う状態で配置されている。前記両者の結合の処理条件は、特に制限されず、温度が、例えば、4~37℃、時間が、例えば、10秒~30分である。前記両者の結合は、例えば、前記液体溶媒中で行うことが好ましい。 Next, the first partition 111 is broken by the sample holding tool 20, and the contents in the first chamber 11 are introduced into the second chamber 12. Then, of the labeled aptamer 18, the labeled aptamer 18 that is not bound to the target 21 is bound to the immobilized complementary strand 19. Further, a sealing member 151 is disposed on the outer surface of the third chamber 13 so as to cover the through hole 14 during the coupling process of the both. The treatment conditions for the combination of both are not particularly limited, and the temperature is, for example, 4 to 37 ° C., and the time is, for example, 10 seconds to 30 minutes. The bonding between the two is preferably performed, for example, in the liquid solvent.
 さらに、前記結合処理中または処理後に、貫通孔14からシール部材151が剥離されると、第2室12から第3室13への通液が可能となる。第2隔壁121は、固定化相補鎖19を通過せず、標識化アプタマー18とターゲット21との第1結合体を通過する多孔性隔壁であるため、標識化アプタマー18のうち、固定化相補鎖19に未結合のもののみが、第2隔壁121を通過して、第3室13に導入される。そして、第3室13において、固定化相補鎖19に未結合の標識化アプタマー18について、酵素182の触媒機能を測定することにより、間接的に、試料中のターゲットを分析できる。酵素182の触媒機能の測定は、酵素182の種類に応じて適宜決定できる。 Furthermore, when the sealing member 151 is peeled from the through hole 14 during or after the bonding process, the liquid can be passed from the second chamber 12 to the third chamber 13. Since the second partition 121 is a porous partition that does not pass through the immobilized complementary strand 19 and passes through the first conjugate of the labeled aptamer 18 and the target 21, the immobilized complementary strand of the labeled aptamer 18. Only the unbonded material 19 passes through the second partition 121 and is introduced into the third chamber 13. Then, in the third chamber 13, the target in the sample can be indirectly analyzed by measuring the catalytic function of the enzyme 182 for the labeled aptamer 18 that is not bound to the immobilized complementary strand 19. The measurement of the catalytic function of the enzyme 182 can be appropriately determined according to the type of the enzyme 182.

That is, the labeled second binding substance bound to the immobilized first binding substance remains in the second chamber without moving to the third chamber. On the other hand, the free labeled second binding substance that has not been bound to the immobilized first binding substance passes through the partition wall and is introduced into the third chamber. Since the labeled second binding substance in the analysis tool of the present embodiment can be, for example, a known amount, the amount of the labeled second binding substance unbound to the immobilized first binding substance is This indirectly corresponds to the target amount in the sample. Therefore, the presence or amount of the target in the sample can be indirectly analyzed by detecting the unbound labeled second binding substance introduced into the third chamber.

 実施形態4Cの分析用具を用いた分析方法の一例について、図面を用いて、具体的に説明する。なお、本発明は、この例には制限されない。 An example of an analysis method using the analysis tool of Embodiment 4C will be specifically described with reference to the drawings. Note that the present invention is not limited to this example.
 図8は、実施形態4Cの分析用具の概略を示す図面である。図8において、図4と同一箇所には同一符号を付している。分析用具6は、第1室11には、アプタマー281に対する相補鎖291に酵素292が付加した標識化相補鎖29が配置され、第2室12には、アプタマー281がビーズ282に固定化された固定化アプタマー28が配置されている。この点を除き、本実施形態の分析用具6は、前記実施形態4Aの分析用具4と同様の構成を有し、その説明を援用できる。 FIG. 8 is a drawing showing an outline of the analysis tool of Embodiment 4C. In FIG. 8, the same parts as those in FIG. In the analysis tool 6, a labeled complementary strand 29 in which an enzyme 292 is added to a complementary strand 291 for the aptamer 281 is arranged in the first chamber 11, and the aptamer 281 is immobilized on the beads 282 in the second chamber 12. An immobilized aptamer 28 is disposed. Except for this point, the analysis tool 6 of this embodiment has the same configuration as the analysis tool 4 of Embodiment 4A, and the description thereof can be used.
 つぎに、図8の分析用具6を使用した分析方法について、図9を用いて説明する。図9は、分析用具6の使用方法を示す概略図である。 Next, an analysis method using the analysis tool 6 of FIG. 8 will be described with reference to FIG. FIG. 9 is a schematic view showing how to use the analytical tool 6.
 まず、分析用具6の第1室11に、保持部202に試料を保持させた試料保持用具20を挿入し、第1室11において、試料中のターゲット21と標識化相補鎖29とを混合させる。前記両者の混合の処理条件は、特に制限されず、温度が、例えば、4~37℃、時間が、例えば、10秒~30分である。前記両者の混合は、例えば、液体溶媒中で行うことが好ましく、前記液体溶媒は、例えば、水、緩衝液、生理食塩水、これらの混合液等の水性溶媒があげられる。 First, the sample holding tool 20 in which the sample is held in the holding portion 202 is inserted into the first chamber 11 of the analysis tool 6, and the target 21 in the sample and the labeled complementary strand 29 are mixed in the first chamber 11. . The processing conditions for mixing the two are not particularly limited, and the temperature is, for example, 4 to 37 ° C., and the time is, for example, 10 seconds to 30 minutes. The mixing of the two is preferably performed, for example, in a liquid solvent, and examples of the liquid solvent include water, a buffer solution, physiological saline, and an aqueous solvent such as a mixed solution thereof.
 つぎに、試料保持用具20により、第1隔壁111を破壊し、第1室11内の内容物を第2室12に導入する。そして、前記内容物中のターゲット21を固定化アプタマー28に結合させ、また、固定化アプタマー28のうち、ターゲット21と未結合である固定化アプタマー28を、標識化相補鎖29に結合させる。また、前記両者の結合処理中、第3室13の外表面に、シール部材151が、貫通孔14を覆う状態で配置されている。前記両者の結合の処理条件は、特に制限されず、温度が、例えば、4~37℃、時間が、例えば、10秒~30分である。前記両者の結合は、例えば、前記液体溶媒中で行うことが好ましい。 Next, the first partition 111 is broken by the sample holding tool 20, and the contents in the first chamber 11 are introduced into the second chamber 12. Then, the target 21 in the contents is bound to the immobilized aptamer 28, and among the immobilized aptamers 28, the immobilized aptamer 28 that is not bound to the target 21 is bound to the labeled complementary strand 29. Further, a sealing member 151 is disposed on the outer surface of the third chamber 13 so as to cover the through hole 14 during the coupling process of the both. The treatment conditions for the combination of both are not particularly limited, and the temperature is, for example, 4 to 37 ° C., and the time is, for example, 10 seconds to 30 minutes. The bonding between the two is preferably performed, for example, in the liquid solvent.
 さらに、前記結合処理中または処理後に、貫通孔14からシール部材151が剥離されると、第2室12から第3室13への通液が可能となる。第2隔壁121は、固定化アプタマー28を通過せず、標識化相補鎖29を通過する多孔性隔壁であるため、標識化相補鎖29のうち、固定化アプタマー28に未結合のもののみが、第2隔壁121を通過して、第3室13に導入される。そして、第3室13において、固定化アプタマー28に未結合の標識化相補鎖29について、酵素292の触媒機能を測定することにより、間接的に、試料中のターゲットを分析できる。酵素292の触媒機能の測定は、酵素292の種類に応じて適宜決定できる。 Furthermore, when the sealing member 151 is peeled from the through hole 14 during or after the bonding process, the liquid can be passed from the second chamber 12 to the third chamber 13. Since the second partition wall 121 is a porous partition wall that does not pass through the immobilized aptamer 28 but passes through the labeled complementary strand 29, only the one that is not bound to the immobilized aptamer 28 among the labeled complementary strand 29, It passes through the second partition 121 and is introduced into the third chamber 13. In the third chamber 13, the target in the sample can be indirectly analyzed by measuring the catalytic function of the enzyme 292 for the labeled complementary strand 29 that is not bound to the immobilized aptamer 28. The measurement of the catalytic function of the enzyme 292 can be appropriately determined according to the type of the enzyme 292.

 実施形態4Dの分析用具を用いた分析方法の一例について、図面を用いて、具体的に説明する。なお、本発明は、この例には制限されない。 An example of an analysis method using the analysis tool of Embodiment 4D will be specifically described with reference to the drawings. Note that the present invention is not limited to this example.
 図10は、実施形態4Dの分析用具の概略を示す図面である。図10において、図4と同一箇所には同一符号を付している。分析用具7は、第1室11には、アプタマー281がビーズ282に固定化された固定化アプタマー28が配置され、第2室12には、アプタマー281に対する相補鎖291に酵素292が付加した標識化相補鎖29が配置されている。この点を除き、本実施形態の分析用具7は、前記実施形態4Aの分析用具4と同様の構成を有し、その説明を援用できる。 FIG. 10 is a drawing showing an outline of the analysis tool of Embodiment 4D. 10, the same parts as those in FIG. 4 are denoted by the same reference numerals. In the analysis tool 7, an immobilized aptamer 28 in which an aptamer 281 is immobilized on a bead 282 is arranged in the first chamber 11, and a label in which an enzyme 292 is added to a complementary strand 291 for the aptamer 281 in the second chamber 12. The complementary strand 29 is arranged. Except for this point, the analysis tool 7 of this embodiment has the same configuration as the analysis tool 4 of Embodiment 4A, and the description thereof can be used.
 つぎに、図10の分析用具7を使用した分析方法について、図11を用いて説明する。図11は、分析用具7の使用方法を示す概略図である。 Next, an analysis method using the analysis tool 7 of FIG. 10 will be described with reference to FIG. FIG. 11 is a schematic view showing how to use the analytical tool 7.
 まず、分析用具7の第1室11に、保持部202に試料を保持させた試料保持用具20を挿入し、第1室11において、試料中のターゲット21を固定化アプタマー28のアプタマー281に結合させる。前記両者の結合の処理条件は、特に制限されず、温度が、例えば、4~45℃、時間が、例えば、10秒~10分である。前記両者の結合は、例えば、液体溶媒中で行うことが好ましく、前記液体溶媒は、例えば、水、緩衝液、生理食塩水、これらの混合液等の水性溶媒があげられる。 First, the sample holding tool 20 in which the sample is held in the holding unit 202 is inserted into the first chamber 11 of the analysis tool 7, and the target 21 in the sample is bound to the aptamer 281 of the immobilized aptamer 28 in the first chamber 11. Let The treatment conditions for the combination of the two are not particularly limited, and the temperature is, for example, 4 to 45 ° C., and the time is, for example, 10 seconds to 10 minutes. The combination of the two is preferably performed in, for example, a liquid solvent, and examples of the liquid solvent include aqueous solvents such as water, buffer solution, physiological saline, and a mixed solution thereof.
 つぎに、試料保持用具20により、第1隔壁111を破壊し、第1室11内の内容物を第2室12に導入する。そして、ビーズ282に固定化されたアプタマー281のうち、ターゲット21と未結合であるアプタマー281に、標識化相補鎖29を結合させる。また、前記両者の結合処理中、第3室13の外表面に、シール部材151が、貫通孔14を覆う状態で配置されている。前記両者の結合の処理条件は、特に制限されず、温度が、例えば、4~45℃、時間が、例えば、10秒~30分である。前記両者の結合は、例えば、前記液体溶媒中で行うことが好ましい。 Next, the first partition 111 is broken by the sample holding tool 20, and the contents in the first chamber 11 are introduced into the second chamber 12. Then, the labeled complementary strand 29 is bound to the aptamer 281 that is not bound to the target 21 among the aptamers 281 immobilized on the beads 282. Further, a sealing member 151 is disposed on the outer surface of the third chamber 13 so as to cover the through hole 14 during the coupling process of the both. The treatment conditions for the combination of the two are not particularly limited, and the temperature is, for example, 4 to 45 ° C., and the time is, for example, 10 seconds to 30 minutes. The bonding between the two is preferably performed, for example, in the liquid solvent.
 さらに、前記結合処理中または処理後に、貫通孔14からシール部材151が剥離されると、第2室12から第3室13への通液が可能となる。第2隔壁121は、固定化アプタマー28を通過せず、標識化相補鎖29を通過する多孔性隔壁であるため、標識化相補鎖29のうち、固定化アプタマー28に未結合のもののみが、第2隔壁121を通過して、第3室13に導入される。そして、第3室13において、固定化アプタマー28に未結合の標識化相補鎖29について、酵素292の触媒機能を測定することにより、間接的に、試料中のターゲットを分析できる。酵素292の触媒機能の測定は、酵素292の種類に応じて適宜決定できる。 Furthermore, when the sealing member 151 is peeled from the through hole 14 during or after the bonding process, the liquid can be passed from the second chamber 12 to the third chamber 13. Since the second partition wall 121 is a porous partition wall that does not pass through the immobilized aptamer 28 but passes through the labeled complementary strand 29, only the one that is not bound to the immobilized aptamer 28 among the labeled complementary strand 29, It passes through the second partition 121 and is introduced into the third chamber 13. In the third chamber 13, the target in the sample can be indirectly analyzed by measuring the catalytic function of the enzyme 292 for the labeled complementary strand 29 that is not bound to the immobilized aptamer 28. The measurement of the catalytic function of the enzyme 292 can be appropriately determined according to the type of the enzyme 292.
