Figure 1. Electrophoresis patterns for MDR1 genotypes by PCR-RFLP based assay. M is a 100 bp DNA marker. Samples 1, 4, 7 and 8 are homozygous CC genotype (Has Bfu CI restriction site). Samples 5 and 6 are homozygous TT genotype (Lack Bfu CI restriction site). Sample 2 and 3 are heterozygous CT genotype.
