Description
本発明は、免疫クロマトグラフィー法によりヒトまたは動物の唾液中の歯周病原細菌を同定・定量を行うために用いる唾液の前処理液に関する。 The present invention relates to a pretreatment solution for saliva used for identifying and quantifying periodontopathic bacteria in human or animal saliva by immunochromatography.
従来から、細菌の検査には抗原抗体反応を利用した検査が行われてきた。一般的な方法として免疫クロマトグラフィー法がある(例えば、特許文献1〜3参照。)。この方法では、ニトロセルロースなどの多孔質膜(孔径:数十μm)の片端に目的とする特定の抗原のみに付く特定の抗体(以後、特異抗体と記す。)が染み込まされており、多孔質膜の中程には同様に特定の抗原のみに付く別の特異抗体が帯状に染み込まされて多孔質膜に固定されている。片端に染み込まされている特異抗体は、予め金コロイド等の粒子で着色されており、その特異抗体が存在している多孔質膜の片端上にサンプル液を染み込ませるとサンプル液中に特異抗体と反応する抗原があれば、その抗原は特異抗体と結び付いて着色粒子を付けた状態で多孔質膜を毛細管現象によってサンプル液を染み込ませた側と反対の片端へ向かって移動して行く。移動の途中で帯状に固定されている別の特異抗体の個所を通過する際に、抗原はその別の特異抗体に捕捉され、多孔質膜上に帯状の染みが現れる。このことによって目的の抗原がサンプル中に存在していること及びその量を知ることができる。 Conventionally, a test using an antigen-antibody reaction has been performed for a bacterial test. As a general method, there is an immunochromatography method (see, for example, Patent Documents 1 to 3). In this method, a specific antibody (hereinafter referred to as a specific antibody) attached to only a specific antigen of interest is impregnated on one end of a porous membrane (pore diameter: several tens of μm) such as nitrocellulose. Similarly, in the middle of the membrane, another specific antibody attached only to a specific antigen is infiltrated in a band shape and fixed to the porous membrane. The specific antibody soaked at one end is colored in advance with particles such as colloidal gold, and when the sample liquid is soaked on one end of the porous membrane where the specific antibody exists, the specific antibody is in the sample liquid. If there is an antigen that reacts, the antigen moves to one end opposite to the side where the sample solution is impregnated by capillary action in a state where the antigen is bound to the specific antibody and colored particles are attached. When passing through the location of another specific antibody fixed in a band shape in the course of movement, the antigen is captured by the other specific antibody, and a band-like stain appears on the porous membrane. This makes it possible to know that the target antigen is present in the sample and its amount.
このような技術を応用すれば前述の口腔内細菌の同定・定量を行うことができそうであるが、口腔内細菌の検査に用いられる主要なサンプルは唾液であるため、唾液中に存在するムチンと呼ばれる高粘性物質及び検出の対象ではない連鎖球菌が多孔質膜の孔を塞いでしまい、またムチンは唾液中に存在する口腔粘膜面から剥がれ落ちた上皮付着細胞を凝集させる働きもするため、これらの物質により多孔質膜の孔が塞がれて口腔内細菌を通過させることができなかった。そのため、本出願人は、以前に唾液の前処理キット及び唾液の前処理方法を提案した(特許文献4参照。)。 If such a technique is applied, it is likely that the above-mentioned oral bacteria can be identified and quantified. However, since the main sample used for the inspection of oral bacteria is saliva, mucins present in saliva Because the high-viscosity substance called and streptococci that are not the target of detection block pores of the porous membrane, and mucin also acts to aggregate epithelial adherent cells that have fallen off the oral mucosal surface present in saliva, These substances blocked the pores of the porous membrane and could not allow oral bacteria to pass through. Therefore, the present applicant has previously proposed a pretreatment kit for saliva and a pretreatment method for saliva (see Patent Document 4).
近年では、特に成人性歯周炎の原因菌としてポルフィロモナス・ジンジバリス(以下、Pg菌と記すことがある。)が重要視されているため、ヒトまたは動物の唾液中のPg菌の有無や量を簡便に検査できれば罹患リスクや現状の罹患状況の把握ができ、極めて多くの人々に有効な情報を与えることが可能である。しかしながら、前記唾液処理方法は特にミュータンス連鎖球菌に対しては有効なものであるものの、Pg菌の検出に用いるとPg菌の菌体表面を変性させてしまい、免疫クロマトグラフィー法による検出はできなかった。 In recent years, since Porphyromonas gingivalis (hereinafter sometimes referred to as Pg fungus) is regarded as an important causative agent of adult periodontitis, the presence or absence of Pg fungus in human or animal saliva, If the amount can be easily examined, it is possible to grasp the risk of morbidity and the current morbidity, and it is possible to provide useful information to an extremely large number of people. However, the saliva treatment method is particularly effective against Streptococcus mutans, but when used for detection of Pg bacteria, the cell surface of Pg bacteria is denatured and cannot be detected by immunochromatography. There wasn't.
抗原抗体反応を利用した免疫クロマトグラフィー法を用いてヒトまたは動物の唾液中の歯周病原細菌を同定・定量を行う際の前記欠点を解消し、簡便な方法で唾液中のムチン及び連鎖球菌の凝集を取り除くことが可能で、且つ歯周病原細菌の菌体表面を変性させないような処理が可能な唾液の前処理液を提供することを課題とする。 Eliminates the drawbacks of identifying and quantifying periodontopathic bacteria in human or animal saliva using an immunochromatography method that utilizes an antigen-antibody reaction, and a simple method for the detection of mucin and streptococci in saliva It is an object of the present invention to provide a pretreatment solution for saliva that can remove aggregation and that can be treated so as not to denature the surface of periodontopathic bacteria.
本発明者等は前記課題を解決すべく鋭意検討を重ねた結果、特定の配合の液で前処理を行うことにより、唾液中の歯周病原細菌の菌体表面を変性させずに唾液を処理し、後の免疫クロマトグラフィー法による検出が可能になることを見出して本発明を完成した。 As a result of intensive studies to solve the above-mentioned problems, the present inventors processed saliva without degenerating the cell surface of periodontopathic bacteria in saliva by performing pretreatment with a liquid having a specific composition. The present invention was completed by finding that detection by the subsequent immunochromatography method becomes possible.
本発明に係る唾液の前処理液は、用いることで簡便に唾液中のムチン及び連鎖球菌の凝集による多孔質膜の孔の目詰まりを防止することが可能であり、且つ、歯周病原細菌の菌体表面を変性させることがないため抗体反応を明確に確認することができる優れた唾液の前処理液である。 The saliva pretreatment liquid according to the present invention can be used to easily prevent clogging of pores of the porous membrane due to aggregation of mucin and streptococci in saliva, and It is an excellent pretreatment solution for saliva that can clearly confirm the antibody reaction because it does not denature the cell surface.

This solubilizes the protein on the surface of periodontopathic bacteria without denaturing the cell surface, allowing periodontopathic bacteria to pass through the porous membrane efficiently.

従来から免疫クロマトグラフィー法では、サンプル液や抗原液が検査器具内をスムーズに移動できるように陰イオン界面活性剤を使用することがよくある。しかし、本発明に係る歯周病原細菌の同定・定量を行うための唾液の前処理液に使用される界面活性剤は、実験の結果から非イオン性界面活性剤及び/または両性界面活性剤である必要があり、ラウリル硫酸ナトリウムやドデシルベンゼンスルホン酸ナトリウム等の陰イオン界面活性剤では、抗体による抗原検出を行うことができない。 Conventionally, in an immunochromatography method, an anionic surfactant is often used so that a sample solution or an antigen solution can move smoothly in a test instrument. However, the surfactant used in the saliva pretreatment liquid for identifying and quantifying the periodontal pathogenic bacteria according to the present invention is a nonionic surfactant and / or an amphoteric surfactant based on the experimental results. It is necessary that an anionic surfactant such as sodium lauryl sulfate or sodium dodecylbenzenesulfonate cannot detect an antigen using an antibody.
本発明に係る唾液の前処理液において、非イオン性界面活性剤及び/または両性界面活性剤は、唾液の前処理液に対して0.02〜25重量%の配合量になるように配合されることが好ましく、0.02重量%未満では抗原抗体反応による検出感度が低くなる傾向があり、25重量%を超えても抗原抗体反応による検出感度が低下し易いため好ましくない。 In the saliva pretreatment liquid according to the present invention, the nonionic surfactant and / or the amphoteric surfactant are blended so as to have a blending amount of 0.02 to 25% by weight with respect to the saliva pretreatment liquid. If the amount is less than 0.02% by weight, the detection sensitivity due to the antigen-antibody reaction tends to be low, and if it exceeds 25% by weight, the detection sensitivity due to the antigen-antibody reaction tends to decrease.

シウム、塩化マグネシウム、硫酸マグネシウム、硫酸マンガン、塩化アンモニウムからな

されてしまう偽陽性を抑制する効果があり、免疫クロマトグラフィー法による検出をより
正確にする効果がある。その濃度は唾液の前処理液中に0.25〜5mol/Lである。
0.25mol/L未満では偽陽性を抑える効果が少なく、5mol/Lを超えると抗原
抗体反応に影響が出て感度が低下してしまうため適さない。
One or more substances selected from the group consisting of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, magnesium sulfate, manganese sulfate, and ammonium chloride, which are blended in the saliva pretreatment liquid according to the present invention, This has the effect of suppressing false positives in which foreign substances that are not antigens are detected by reacting with antibodies, and has the effect of making detection by immunochromatography more accurate. The concentration is 0.25 to 5 mol / L in the pretreatment solution of saliva.
If it is less than 0.25 mol / L, the effect of suppressing false positives is small, and if it exceeds 5 mol / L, the antigen-antibody reaction is affected and sensitivity is lowered, which is not suitable.
本発明に係る唾液の前処理液は、抗原である歯周病原細菌の多孔質膜中の移動を容易とするために、pH3〜8であることが必要である。pHが3未満であると偽陽性が強く現れ検出精度が低下してしまい、一方、pH8を超えると抗原の菌体表面に変性が生じてしまい、抗体による抗原検出ができなくなる。 The saliva pretreatment liquid according to the present invention needs to have a pH of 3 to 8 in order to facilitate movement of periodontopathic bacteria, which are antigens, in the porous membrane. If the pH is less than 3, false positives appear strongly and the detection accuracy is lowered. On the other hand, if the pH is more than 8, denaturation occurs on the surface of the antigen cell, making it impossible to detect the antigen using antibodies.
そのため、本発明に係る唾液の前処理液には、緩衝作用付与物質及び水を配合している。緩衝作用付与物質は、2以上の物質の組み合わせからなり、塩酸−塩化カリウム,塩酸−トリス(ヒドロキシメチル)アミノメタン,塩酸−グリシン,グリシン−水酸化ナトリウム、クエン酸−リン二水素ナトリウム、クエン酸−クエン酸ナトリウム,リン酸二水素ナトリウム−リン酸二水素ナトリウム,炭酸ナトリウム−重炭酸ナトリウム,酢酸−酢酸ナトリウム,酒石酸−酒石酸ナトリウム,酒石酸−トリス(ヒドロキシメチル)アミノメタン等が例示される。この群より選ばれる1種または2種以上が配合されることが好ましい。 Therefore, the pretreatment liquid for saliva according to the present invention contains a buffering substance and water. The buffering substance is a combination of two or more substances: hydrochloric acid-potassium chloride, hydrochloric acid-tris (hydroxymethyl) aminomethane, hydrochloric acid-glycine, glycine-sodium hydroxide, citric acid-sodium dihydrogen phosphate, citric acid -Sodium citrate, sodium dihydrogen phosphate-sodium dihydrogen phosphate, sodium carbonate-sodium bicarbonate, acetic acid-sodium acetate, tartaric acid-sodium tartrate, tartaric acid-tris (hydroxymethyl) aminomethane and the like. It is preferable that 1 type, or 2 or more types selected from this group is blended.

It is preferable that it becomes the range of 0.01-3 mol / L in this pre-processing liquid.
