Fig. 2. (A) Microarray map. VP1, positive control. The designation of each probe is shown in Table 2. Both the 4-base deletion and SNP 180 genotypes of MDR1 were clearly identified using an oligonucleotide microarray system and either the synthesized standard sequences (B) or clinical dog blood samples (C). WW, WM, and MM indicate wild-type homozygote, heterozygote, and homozygote 4-base deletion mutation genotype of MDR1, respectively. T/T, T/G, and G/G indicate allele-specific genotypes of SNP 180.
