Abstract:
The present invention provides a microchip for an immune agglutination reaction, comprising: (a) an inlet through which a sample and a probe are introduced, wherein the probe includes an antibody having binding affinity to an object of analysis in the sample; (b) a reaction channel in which, while the sample and the probe introduced through the inlet move, an immune agglutination reaction occurs between the object of analysis in the sample and the antibody; and (c) a light scattering measurement unit for measuring the degree of light scattering of a reaction product generated from the immune agglutination reaction of step (b). The microchip of the present invention requires no separate apparatus and procedure for helping the reaction and movement of the sample. The microchip of the present invention can promptly determine, within 10 minutes, the presence or not of pathogen and the infection or not with pathogen using a small amount of sample, and thus is very useful in diseases which need to be promptly diagnosed.

Abstract:
A DNA chip using an oligo-gene chip, a diagnostic kit for testing genes and a method for genetic information are provided to detect viral genes existing in porcine blood or tissue, test genotypes with high specificity and acquire genetic information rapidly at low cost through one test different from a conventional testing method requiring several steps. A DNA chip comprises at least one sequence structure of an oligo-gene probe of a table 1, wherein the sequence structure includes a target gene region of a table 2. In the table 1 and 2, R is A or G, Y is C or T, C1 is a positive control, and C2 is a negative control. A diagnostic kit for testing PMWC related virus PRRSV, PCV2, and PPV genes is characterized in that an amplification means is each of a primer for RT-PCR primer sequences described in table 3. In the table 3, a Cy3 fluorescent material is attached to 5' of PR_NA-F, PR_EU-F, PC-F, and PP-F primer, R is A or G, W is A or T, K is G or T, and Y is C or T. A method for testing genetic information of the PMWS related causing virus comprises the steps of: (a) extracting RNA from porcine serum or blood; (b) amplifying the extract through multiplex RT-PCR or multiplex PCR; (c) hybridizing genes of the amplified each viruses into an oligo gene probe; and (d) identifying genetic information of specifically bonded viruses during the hybridization.
