Abstract

The presence of a nucleic acid target, molecule or ligand can be detected by hybridization, antigen-antibody reaction or receptor-ligand binding. This is reported by the strategic positioning of a first probe and a second probe attached to a small particle of electrical conductor which closes an electrical circuit, thereby reporting the event. A myriad of potential applications of this technique include the identification and detection of small amount of nucleic acids by hybridization, the detection of molecules such as toxins and carcinogens by antigen-antibody reaction and the detection of other molecules by receptor-ligand interaction. The method can also be adapted to assay the quantity of a given substance using the principle of competitive binding.

"Antigen" means a substance with a molecular surface structure that triggers an immune response substance, that is, the production of antibodies, and / or specific antibodies Reaction (antigen / antibody reaction). An "antibody" is a protein (immunoglobulin)) that recognizes and binds to an antigen as part of an immune response. "Molecular probe" means any nucleic acid, protein molecule, or other molecule, Has the ability to specifically bind to other molecules of the same or different type. In general, nucleic acids specifically bind to nucleic acids that exhibit sequence complementarity. Therefore, a probe (in this example, a nucleic acid molecule) having the following sequence-AGGCGTA (from the 5 'end to the 3' end)-specifically binds to another strand of DNA, which contains The region of the following sequence TACGCCT (from the 5 'end to the 3' end), where A, T, G, and C represent adenine, thymine, guanine, and cytosine, respectively.

Description of the Invention (8) Figure 11 is a schematic diagram describing another set of probes. The number of repeated combinations of the probes is more than the correct number of repeats in a given patient, causing overhanging probes and joints. Failure of function. Description of the preferred embodiment In the first figure, the basic unit comprises a wire 1, a switch 2, a battery 3, an ammeter, a light bulb or a microprocessor 4, and a reaction "well" 5, which contains two electrodes 6 And a small gap 7 between the electrodes. The circuit was originally open, but when the iron beads were located between the electrodes, then the switch 2 was turned on to complete the circuit and cause current, which can be detected by the ammeter 4. In Figure 2, the wafer 8 is a reaction "well" plus the electrode mentioned in Figure 1. In the center of this wafer is a "well" 5, which may be a little recessed, with a covalently bound molecular probe 9 on the wall, which is specific to the molecule (target) to be found / analyzed. The needle can be a nucleic acid (left panel) or an antibody (right panel). Two electrodes 6 are opposite to any wall of the "well". When manufacturing multiple wafers in a microarray, the "well" does not have to be recessed (See Figure 4.) The advantage of having a flat "well" is that at the end of the reaction, it is easier to remove unbound excess iron-bound probes (described in Figure 3) by applying a magnetic field. In Fig. 3, for example, some conductive beads of iron beads 10 are located between two electrodes 6 and are bound by sandwiched target molecules 11 which are attached to the first probe of the binding "well". Needle 9 and a second probe 12 bound to iron beads. In the left panel, this probe is a nucleic acid molecule, which can identify different parts of the target nucleic acid.

In this method, the 'microprocessor has computing power, and multiple agents / molecules can be measured in a portable device at the same time (multiple) debt. The tube g13 is disposable and can be replaced with another = the same to determine different groups of molecules. Two or three repetitions can be embedded for pre-failure af ° and ‘pre-test with negative control and post-test with positive control (if the test result is negative) to ensure the test performance. In Figure 5, the analyte is tied to the test, well "5", sandwiched between two probes. One of the probes 9 is bound to, the well, and the other 12 is bound. To the iron beads 10, the iron beads are in contact with the electrode 6. Adding a test sample containing a sufficient concentration of the analyte causes the competitive binding and substitution of the second probe attached to the iron beads, thus blocking this Circuit (closed). In Figure 6, the analytes and iron beads sandwiched between the electrodes are gradually changed in a series of arrayed wafers, allowing the detection of unknown concentrations as explained below. In Figure 7, the pre-bound beads were not used. The amount of beads-bound probes was less than that of the analytes. This result is a combination of the analyte-bound particle probe 15 and the free Analyte 11 competes with limited binding, wells, and needles 9. The gap between the electrodes is reduced to accommodate only one bead. The left panel shows the bindings that are completely occupied by the analytes, wells, and probes. , Without the attachment of the bead-bound probe (closed). Right The panel shows bead-bound probes, which bind to the analyte molecules attached to the bound, well, and probe (on). In Figure 8, a microarray with thousands of such wafers is recorded, The format of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X297 public love) (Please read the precautions on the back before filling this page), \ Tan · -12- 1245895 A7 B7 V. Description of the invention (1G) Kai " The total number of signals is the result of binding of the analyte-binding particle-bound probe to the "well" -bound probe. A "closed" signal is recorded on a wafer that is bound to a "well" probe by a free analyte that is not attached to a bead-bound probe. The ratio of the "on" to "off" signals depends on the relative concentration of the probe and free analyte bound to the analyte and the bound particles. The enlarged view of the cartridge 13 shows that some wafers are open, while some wafers are closed. The known molar concentration of the bead-bound probe allows calculation of the analyte concentration. In Figure 9, the principle of measuring the number of CAG repeats in Huntington's disease is illustrated. A description of this method can be found in Example 9. The bead-bound probe 17 is designed to have the following sequence in the probe detection area: CTGGAAGGA, and the probe detection area of the "well" probe 18 has the following sequence: J: GGTGGCGGCTGTTGCTGCTGCTG. In the figure, the upper strand 19 is the target gene with four sets of “CAG” repetitions present in this particular patient. Only this region that is complementary to the probe is described as having the actual nucleic acid sequence. The other endpoints (5, 20 and 3 '21) are indicated by arrows. The hybrid binding beads 17 and the "well" probe 18 are described in the same manner as previously described. The underlined portion of the probe (above the figure) indicates the unrepeated portion of the adjacent repeating region. In the figure, these two probes have a combined number of repetitions corresponding to the target (4 correct). Therefore, the 5 'and 3' ends of the two probes are grouped together and can be ligated by an enzyme (DNA ligase). In Figure 10, only the sequence of a different "well" -bound probe 22 is explained because the beads-bound probes are the same. The "well" probe 22 is placed in another electrobiochip in the same microarray. The “well” probe 22 described here has only two repetitions. When hybridizing with the target, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -13-(Please read the Note for this page, please fill in this page again)-口 _ r 线 丨 1245895 A7 B7 V. Description of the invention (11) will create a gap between the two probes. These two probes cannot be joined. In Fig. 11, another probe "23" that incorporates "wells" has too many repetitions (5). Therefore, the excess portion will have "overhangs" 24 after hybridization. It also has no bonding effect. Obtaining the sample allows the air containing the putative target to foam through the appropriate solute. Solid or liquid can be dissolved in solution. Requires intact cells and tissues to be ruptured, opened or prepared to release the molecules to be tested. Device (Electro-Biochip) In its simplest design, this electro-biochip consists of a small test "well" containing two wires inside it with a small gap between the two wires. A molecular probe is bound to the gap, and the probe is specific to the putative target. The other element is a second specific probe, which is bound to the beads of the electrical conductor. Reaction Add the sample to the wafer. Add a second probe (before, during, or after adding the sample) in excess of the target amount. Allow the reaction to occur. After the reaction, the unbound probe and iron beads are sucked away by generating an appropriate magnetic field. Finally, record the results. Quantify the width of the gap between the two electrodes and the amount of the "well" probe, and therefore the sandwiched "well" probe / target / bead-bound probe is designed on the opposite side of the wafer ( Record “on” signal instead of recording “off” signal) The array can be changed to measure the amount of target in the sample to be measured.

In addition, the probe can be designed in such a way that when hybridized with the target, the two ends of the probe have physical similarity so that DNA ligase (an enzyme that covalently binds the aggregated DNA strands) can join the two ends to enhance the binding between the iron beads and the "well".

Description of the invention (13) Nucleic acid probes or antibodies can be covalently bound to different substances. The first antibody is bounded by an open circuit. The small gap between the two ends is bonded to the wall of the container (Figures 1 and 2). The two electrodes are connected to the microprocessor by wires on the chip, which form and / or monitor the remaining circuits. The second specificity probe is bound to small free iron beads by similar techniques. When the target is present and under proper conditions, the target binds and is sandwiched between the two probes (Figure 3). The position of the first probe brings the iron beads bound to the second probe into contact with the electrode and closes the circuit, allowing current to be passed when the battery provides a potential difference. The concentration of the target ranges from a single molecule to binding Of beads There are usually many needles, providing robustness of the design. However, sensitivity cannot be compromised. This assembly can theoretically detect the presence of a single molecule. In addition, when used to detect specific nucleic acid sequences, no previous amplification is required. This method It is versatile and can be used to detect DNA, RNA, proteins and other large molecules. Manufacturing of microarrays Multiple single wafers can be manufactured into microarrays (Figure 4). These individual wafers can be manufactured to detect different molecules . Two or three duplicates of the same wafer can be manufactured on the same microarray for quality assurance purposes. A secondary antibody with bound iron beads is housed in a cassette containing the microarray. The cartridge is designed to be slightly vacuumed (it has a section that can be expanded to accommodate more samples) in order to suck in a predetermined volume of sample. The cassette entry / exit allows samples to be introduced into the cassette. Reading device A portable device is constructed with a slot for receiving a cassette.

This can be achieved Because the unbound analyte and the bound analyte compete for the iron bead-bound probe or the "well" probe, the pre-positioned iron bead is replaced. Now the result is an open circuit ( Close). A microarray can be fabricated with a large number of wafers on it, each slightly varying in width between the two electrodes, and in the amount of arrayed clamped analytes / probes that bind iron beads. The addition of an unknown amount of analyte caused some of the probes to bind to the iron beads to be replaced. Although this will not affect wafers with wider gaps and more probes that are bound to the iron beads (maintained "on"), but With fewer gaps and smaller numbers of knots ^ Probe iron beads of said sheet closes.

Description of the invention (16) ^ ear) The second bead-bound probe. Fragments are separated by competing for thousands of wafers that are still far behind in number (compared to analytes that are free and bound to bead-bound probes), and using known amounts of bead-bound probes. The concentration can be calculated by the microprocessor and by the ratio of the opening date. There must be a large number of electrobiochips in a microarray for accurate results. Wafers are also manufactured so as to accept only one conductive bead to increase accuracy. In order not to disturb the kinetic equilibrium, the bead-bound probes that are not attached to the bound "wells" are not sucked away by the magnetic field. A series of measurements were performed and averaged to obtain the final results. Example Example 1 Nodules The ribonucleoprotein ribonucleic acid (rRNA) of Mycobacterium tuberculosis (causing tuberculosis) is the target of detection in the AMPLIFIED ™ Mycobacterium Tuberculosis Direct Test (Reference ι-ίο). Amplification is required (Transcriptional Amplification (TMA)). The method of the present invention only requires a simple method to rupture the bacterial cell wall to release rRNA. Using the electrobiochip of the present invention, as few as one copy can be detected No prior magnification is required. Example 2 A timely laboratory diagnosis of acute myocardial infarction (heart disease) has potential life-saving characteristics because therapeutic interventions can be set up. Such interventions are not inherently non-hazardous and require an accurate test. Until now, the tests have either been insufficiently sensitive or non-specific. For example, the earliest myocardium The plug indicator is an increase in plasma myoglobin, which can be detected 6 hours after infarction (References 11-14). However, myoblasts-19-f (please read the precautions on the back before filling this page) Paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) 1245895 A7 ____B7______ V. Description of the invention (17) The element also exists in skeletal muscle and its rise is not specific for myocardial injury, so plasma troponin is required Confirmation of the second analysis (http: //demapoc.mah.roche.eom/content/products/c read / c_read.htm), which is a marker of slower rise than myosin. Earliest in acute myocardial infarction The ability to detect trace cardiac troponin T at the same time requires both specificity and sensitivity. This requirement is now made possible with our electrobiochip. In this application, competition as described in the "Quantitative" section above is used The principle of sexual binding. The analyte is cardiac troponin τ and the second probe is an antibody raised against cardiac troponin τ. The antibody will preferentially bind to cardiac troponin T. Two different antigens determine And do not interfere with each other (the epitopes are not too close to interfere with the binding of the secondary antibodies). In addition to detecting the circulating cardiac troponin τ in the early stages of acute myocardial infarction that cannot be detected by the prior art ( It may exist after the onset of acute myocardial infarction in a time period much shorter than 6 hours) 'This application also allows the quantification of the plasma concentration of this protein (through serial dilutions of cardiac troponin τ of known concentration, Reach the inflammation of the instrument immediately.) Example 3 In scientific research, scientists usually need to study gene performance. In multicellular organisms, cell lines with the same set of genes are specialized to perform many body functions, such as covering the surface of the body (the outer skin or skin), absorbing fluids and electrolytes (the intestine), and interacting with the outside world (the nervous system). ). As a result, "the cell needs a tool that appears in these specialized cells" The specialized cell does not appear in other differentiated cells. At present, gene expression is performed by fluorescent probes or other methods, individually or using a recently-discussed microarray, which is a printed or attached molecular probe that can interact with messenger RNA Hybridization and qualitative existence or non-existence -20- (Please read the precautions on the back before filling this page) This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) 18! 245895 V. Description of the invention ... fruit. Needless to say, these microarrays do not have the ability to quantify mRNA, and mRNA can be expressed at a low amount. Low-volume performance is also important because we know that low-volume performance must be synonymous with the production of very small amounts of protein because the concentration of cellular protein is dynamic and represents a balance between production and disruption. With the present invention, the quantification of mRNA and the corresponding protein are simplified, as described in the "Quantification" section above. Example 4 The detection of major changes is a method for detecting specific diseases, which is passed down from generation to generation (hereditary) in germ cells. With the conventional method based on the amplification of gene regions, the detection of single point mutations (sometimes very large) in genes has the disadvantage that large fragments cannot be amplified, and therefore restricts the economic and systematic study of a specific The ability to point mutations in human genes. With the present invention, paired probes (binding "wells" and binding beads) can be designed as unmutated genes (found in public databases) with known sequences. The paired needles are designed to complement the continuous elongation of the sequence. It has been researched on demand that many pairs are designed to cover the entire length of the gene, and different bound probes are attached to individual electrobiochips, and the detectable area 2 is in the unique discriminator of Card II. In this way, and using the device's special: configuration 'makes it reusable', it can carry out fast, economical and systematic research on gene mutation. EXAMPLES Many cancer lines are translocated to another gene or to another gene (chimeric gene). Examples are too many follicular carcinomas that cannot be listed and include 3 sacral glands, specific acute osteoblastic leukemia 'and many soft tissue sarcomas, such as synovial sarcoma and exoskeleton myelochondrosarcoma. This paper size applies Chinese National Standard (CNS) A4 (210X297 public love) -21-1245895 A7 B7 V. Description of the invention (19) Although the identification of mRNA transcripts (chimeric transcripts) of these chimeric genes It can be easily performed by the conventional polymerase chain reaction for amplification and electrophoresis for identification based on the amplified product. This method is slow and laborious. According to the present invention, a pair of probes that hybridize to two components of the chimeric transcript can be prepared. One probe is a probe bound to a "well" and the other probe is a probe bound to a conductive bead. Therefore, a positive identification can be achieved, even if trace samples are taken from the tumor or blood (if the tumor is leukemia or those who can easily enter the bloodstream at an early or late stage of the disease) by means of fine needles. Many different cancers can be screened simultaneously in this way. Example 6 Many diseases have viral causes. An example is HIV (infected with a human immunodeficiency virus). Although this disease can be controlled by antiviral agents, these agents are very expensive. Because the virus is susceptible to mutation, not all patients respond to the same agent at different times. Monitoring viral load is one way to determine drug efficacy and disease status. With this method, viral load research is made highly accurate, simple, fast, and cheap. The principle of analysis has been described previously. If the gene sequence is known, this method can be used to study any virus. Example 7 Many infectious diseases have similar manifestations. For example, anthracnose, influenza, dengue fever, smallpox, common cold, roseola, etc. The initial symptoms include contradiction (generally uncomfortable), fever, myalgia, and non-specific rash. In order to allow the attending physician to accurately identify the majority of these diseases with similar symptoms but with greatly different results, the present invention can be applied to the entire panel micro-22- (please Please read the notes on the back before filling this page) This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 1245895 A7 B7 5. Detecting the amount of invention description (so early). Many patients do not even need to be hospitalized for observation and can be sent home because of the positive identification of the cause, while saving money and avoiding danger to the patient (if they need to be cared for in a hospital that may hide harmful microorganisms). fExample 8 Monitoring of harmful substances in drinking water and food (or animal feed), such as mad cow disease agents (bovine spongiform encephalopathy (BSE)) is hindered by the high cost and low sensitivity of the test (Reference 15 -20). For example, cattle with bse have trace amounts of substances in the brain fluid (cerebrospinal fluid). Sensitivity tests not only detect diseases early, but they are also exempt from animal slaughter. Humans infected with the disease by eating sick cattle can also be tested. By using specific antibodies discovered by other researchers, the present invention can significantly reduce costs and time to identify pathogenic agents. Example 8 Many hereditary diseases are caused by too long a specific region of a hidden repeat sequence. For example, Huntington's disease, a constant fatal disease, is caused by the presence of "CAG" in the Huntingtin gene located on chromosome 4 more than 36 times (http: / /www.ncbi.nlm.nih.gQv/entrez/dispomim>cgi?id:::=141 100) o In order to measure the number of repeats in the human Huntingtin gene, the conventional method is to use PCR. The invention simplifies the measurement of the number of iterations. Therefore, the probe is designed to be adjacent to the invariant part of a gene adjacent to the overlapping sequence (http://www.ncbi.nlm.iiih.gov/entrez/cuierv.fcgi?cmd=Retri eve & db = nucleotide & list uids = 450395 & dopt = GenBank) 〇In addition to the invariant sequence adjacent to the repeat, combined with the "well" probe to carry -23-(Please read the precautions on the back before filling this page} This paper size applies to China Standard (CNS) A4 specification (210X297 mm) 1245895 A7 B7 V. Description of the invention (21) Number of different repeats. Probes that bind beads carry the same area on the opposite side of the repeat and are one Or duplicates. A person with a specific number of repeats, such as 5 "CAG" repeats, if the probe that binds the well contains 4 repeats and the probe that binds the beads contains 1 repeat, when hybridized, it will have The two probes are perfectly arranged end-to-end. Other wells containing probes that bind "wells" that measure more than 4 (such as 5 or more) or less than 4 (such as 3 or less) will hybridize but will not produce perfect End arrangement. Using DNA ligase (covalently binding two DNA strands, the strands are aligned Complementary strands with closely adjacent ends), the two probes can covalently join. Repeated probes with a combined number of more than 5 will have overhanging strands that cannot be joined to another strand and have a lower than 5 The same combination of repeated probes is the same, because there is a large gap between the two probes. After the hybridization and ligation reaction, the adjustment of the reaction conditions caused the probe and target to separate (denaturation), resulting in other non-4CAG weights. The "shut-off" of the electrobiochip combined with the "well" probe. The result is a fast and accurate measurement of the number of CAG repeats in the human Huntingtin gene. The method of the present invention is applicable to Any kind of genetic disease with a repeated number of changes. -24- (Please read the notes on the back before filling out this page) This paper size applies to China National Standard (CNS) A4 (210X297 mm) 1245895 A7 B7 V.
