METHOD OF DOUBLE ALLELE SPECIFIC PCR FOR SNP MICROARRAY
First Claim
1. A method of double allele specific polymerase chain reaction (PCR) for single nucleotide polymorphism (SNP) microarray, comprising:
- (a) amplifying a nucleic acid sample by multiplex SNP PCR using at least a primer set which recognizes a single nucleotide polymorphism (SNP) to obtain an amplified product;
wherein an interchelating agent is added into PCR, and the interchelating agent is SYBR®
green dye; and
(b) contacting the amplified product with a SNP microarray fixed a probe suitable for determine the identity of SNP to genotype SNP,wherein the primer set contains at least four allele specific primers, which at least two allele specific primers bound with a sense strand of the nucleic acid sample, and 3′
terminal nucleotides of the two allele specific primers are complementary to an allele specific site; and
at least two allele specific primers bound with an antisense strand of the nucleic acid sample, and 3′
terminal nucleotides of the two allele specific primers are complementary to the allele specific site.

Abstract
The present invention provides a method of double allele specific polymerase chain reaction (PCR) for single nucleotide polymorphism (SNP) microarray, the method provides the allele specific site as the 3′ teiiiiinal nucleotide of forward and reverse primers, it does not require a primer having specific nucleotides. The method of the present invention is easily to design the primer based on flanking region of the allele specific site, and to perform multiplex SNP PCR applying with an interchelating agent, then to detect by a SNP microarray.
