Jin and biological materials: the required sample of the sample, the biochemical exploration of 1287581 and the subject matter are reduced, and In the past, the amount of traditional specimens was reduced by more than 2 times.

Class: However, until now, the development of its gene chip has been divided into two major production days (four) wafers: the general glass wafer is fixed on the wafer by a special square, and arranged neatly into p 'Clothing is the required genetic chip; this kind of wafer can not be used in related fields. The main reasons are as follows: , c high, the threshold of large glass processing technology is high, and the cost is relatively high. 匕 It is not a general laboratory or The testing unit can afford it. (2) Fluorescence coloration and hybridization reaction used in glass carrier wafers. • High quality requirements of sample (ribonucleic acid) and light reaction steps. 1 The faulty cursor (cy3 and cy5) is costly and difficult to use. Fix j 3) The result of the fluorescence coloration analysis, the scanner required is a special scanner, and the cost is not high enough for the general experimental unit.龙二)·Nylon film wafer···························· Compared with the glass wafer; the nylon mold wafer preparation 1287581 Niu Yi μ household, the low technical threshold, and the chemical coloring method used: the simple method, the low cost of the tanning agent, but the sample required for this method (Nuclear, Tang nuclear is large, chemical color analysis results without automated analysis, = leading to serious impact on experimental recording and accuracy; therefore, the nylon mold wafer is gradually replaced by glass-ion wafers. ^ In addition to this Whether the glass wafer or the nylon mold wafer is prepared, the dot matrix device is used, and the price of the automated dot matrix device is also quite 叩, and the operation of the instrument is not easy. In the current situation, even if the wafer inspection can be operated: The research laboratory is also unable to independently prepare the required wafers, and must be transferred to a specific biotechnology company for execution; therefore, the above-mentioned conventional gene chip preparation method does not meet the needs of actual use. 1287581 SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to enable a biochip wafer technology platform that is low in cost, easy to operate, and highly efficient by the method of the present invention. The function and application of the present invention can be effectively utilized. Another object of the present invention is to achieve the practical application of the gene wafer to various related fields by the method of the present invention. For the above purpose, the present invention is a microcellular nucleic acid. A method for detecting a wafer, comprising the steps of: a. selecting a nylon mold wafer, using a manual dot-trigger to arrange the desired nucleotide fragments in a neat array on the wafer; b. drying naturally after manual dot-dot, Then, using a nucleic acid fast fixer (cross_linker), the nucleotide fragment is fixed on the nylon mold to complete the wafer preparation; c. collecting the general blood as the sample; d. extracting the ribonucleic acid in the blood and linearly Amplification; e_reverse transcription assay synthesizes a sufficient amount of complementary deoxyribonucleic acid (cDNA) and marks it to form a probe as a probe; f. probes the above-mentioned wafers and markers Hybridization and post-hybridization treatment; g. chemically coloring the wafer after the hybridization reaction with the marker H_ Automated analysis of the image results of the above chemical color reaction. 1287581 ί If, the above-mentioned steps are highly efficient, the gene wafer operation technology is flat. The cost is low, the operation is easy, and the application can be effectively utilized. It is true that W's work is in various related fields. 曰: The practical application of the earth-based wafer [Implementation j, please refer to the "1st, 2nd, 2nd, 2nd, and 闰" diagrams, which is the flow of the present invention.

A plurality of holes 142 are disposed in the center of the striking layer 14 , and a block of 4·5×4·5 cm is selected at the center of the striking layer 14 and is prepared at a pitch of 3 mm. One row (row: 14; column: 14) hole with an inner diameter of 1 2 mm 1 1287581 4 2 'After the micro-suction tube is inserted (ie, at the dot); the manual tapping machine is used as follows: The starter handle 141 of the active switch 1 is opened to occupy the layer 14 and the wafer is placed on the wafer placement layer i 2 . —2· Cover the dot layer 14 , the wafer fixing layer 13 automatically fixes the wafer to the oligo-nucleic acid, and directly penetrates the hole in the central layer of the layer 1 4 2 Oligonucleotides can be used. b. After the manual dot-drying, it is naturally dried, and then the nucleic acid fast fixator day (cr〇ss-lmke"), the core: acid fragment is fixed on the nylon mold, that is, the preparation of the nucleic acid fast fixer is completed. The high-energy energy of 12QQ Joule is used to join the parent fork, and the nucleotide fragment is fixed on the nylon mold; C. The general blood is collected as the sample, and only 1 c c of blood is collected when collecting the sample. The sample can be reacted to obtain 40 units of cDNA (complementary deoxyribonucleic acid), and only 4 units of cDNA are required for each wafer experiment; d_ extracting the ribonucleic acid in the blood and linearly amplifying; e· The reverse transcription assay synthesizes a sufficient amount of cdNA and marks it to form a probe as a probe; f. performs probe-marking reaction, hybridization reaction, and post-hybridization reaction on the above-mentioned wafer and the target substance. (p〇s 卜 Hybr1dizat•丨〇n) treatment, the probe labeling reaction time and hybridization reaction time is 24 hours; g· chemical reaction of the wafer after the hybridization reaction with the marker is 1287581, after the hybridization When the reaction is processed, its detection The detection time is 30 minutes, which can accelerate the color reaction of the reaction after the hybridization, so that the background color is not excessively colored due to excessive color formation, and the reaction time can be reduced. False Positive Reaction), and after the hybridization and the membrane cleaning before the fixing step, a self-adapting Washing buffer can be used, and the pre-coloring film (Membrane) can be self-adjusted. Detection buffer; h. Automated analysis of the image results after the above chemical color reaction, and the image results after the color reaction can be automatically analyzed by the general density (Density) analysis software. First, we first analyze the experimental results with the Statistical Package for the Social Sciences Ver. 10.0 and learn from the Receiver Operating Characteristics curve that it is determined on each wafer used for this time. After comparing 22 genes with normal gene expression values, if there are 11 or more genes with more than twice the excess table , that is, positive reaction (positive, ten), when 11 or less, it is determined that the wafer is negative (negative, one), so that the most reasonable statistics will be obtained, and the sensitivity and specificity will fall at the most appropriate point. Therefore, this data is used as the standard for interpretation. Please refer to Figure 5, in order to confirm the feasibility and sensitivity of this method, we specially carry out the experiment in the glass, and the K-ras carcinogenesis established before the first 1287581 After the gene-stable transfected adrenocortical cell (K-ras MSTAC) is placed in normal blood, the wafer is analyzed by reacting with the detection wafer of the present invention. Positive control (+) was used and the positive control system employed β-actin 16. As a result, when there are 22 genes on the wafer and 20 K-ras MSTAC cells are contained in the blood of 1c.c., 16 genes are overexpressed, and the wafer is interpreted as a positive reaction, that is, 72.72 The % gene showed positive (+), greater than 50%; and when 1c_c contained 5 K-ras MSTAC fine monthly packets, 'Bei U had 12 genes overexpressed'. This wafer was interpreted as a positive reaction, that is, there was 54.55% of the genes showed positive and greater than 50%; but when the number of cells was reduced to 2, only 3 genes were overexpressed, the wafer was interpreted as a negative reaction, that is, only 13.64% of the performance was positive and less than 50%; when the number of cells is only one, the number of over-expressed genes is less than three and less than 50%, so the result is still interpreted as a negative reaction. Therefore, the detection of the wafer of the present invention is indeed feasible and as long as the number of blood cells per c.c is greater than 5, our detection wafer can accurately detect the activation of the K-ras gene in the blood. Please refer to "Figure 6 and Table 1" for the purpose of detecting the reaction performance of cells in the blood of various cancer patients and specific gene groups by using the micro cell nucleic acid detection wafer technology platform, and the present invention utilizes the instant polymerase chain reaction ( Real-Time PCR) confirms the detection results of the micro-cell nucleic acid detection wafer technology platform. As shown in the figure: wherein the fourth figure is 12 1287581 ^ = : 2 the result of the reaction of the ribonucleic acid of the blood of the cancer patient with the diagnostic day of the present invention; and the eosinophilic because of the instant polymerase chain error "3 is an instant polymerization Enzyme chain-locking reaction ' __ ffl —, ', 贞 reaction is another technique for detecting RNA expression: using the same gene in the diagnostic wafer used in the present invention and whether the gene amplification performance is measured by the K ° _ chain reaction The situation is a magnified filament - it can be seen that the gene detected by the 9 (4) on the wafer is also amplified in the instant polymerase chain reaction.

(3) Sample processing: Up to now, because of the high amount of nucleic acid required for wafer experiments and the high quality requirements, the most commonly used glass wafer microarray analysis is used as an example, and the required nucleic acid is 八〇8/8 280 strict requirements must be above 1.8, and the required amount must reach 2pg (Total RNA 100pg), so that the practical application of the wafer is limited to microbes and tissue containing a large amount of ribonucleic acid, not only the sample is not easy to obtain, but also hindered The generalization and development of wafers. To this end, the present invention improves the traditional experimental mode, establishes a new method of sample processing, linearly amplifies the ribonucleic acid to solve the problem of limited specimens, and stabilizes the reverse transcription test to synthesize a sufficient amount of cDNA, so even a small amount of ribonucleic acid in the sample It is also possible to carry out wafer reactions. At present, not only the quality requirements of RNA are relaxed (only A26〇/A28〇: 1.2), but only 1c_c of Whole Blood can be used to carry out 40 units of cDNA, which is required for each wafer experiment. The cDNA requires only 4 units.
