A representative agarose gel electrophoresis of ASP-PCR. a The SNP rs16969968 and b the SNP rs1051730 were genotyped with two separate reactions for each sample: one using wildtype-specific primer (wt) and the other using mutant-specific primers (mt). L 100 bp DNA ladder and B blank water sample. Samples (S30, S31, and S33) are wildtype homozygous and sample S32 is heterozygous for both SNPs
