Gel electrophoresis of C3435T polymorphism from tissue samples. Left: The last lane from the right is 50 bp DNA ladder. Samples in lanes 1, 3 and 5 represent the PCR products and samples in lanes 2, 4 and 6, are the digest products of each sample, respectively. Sample in lane 2 is the mutant homozygous uncut TT genotype (197 bp). Sample in lane 4 represents the wild type cut CC genotype (158 bp and 39 bp). Sample in lane 6 represents heterozygous CT genotype (197 bp, 158 bp and 39 bp). Right: Gel electrophoresis of C3435T polymorphism from blood samples. The first lane from the left is 50 bp DNA ladder. Samples in lanes 1, 3 and 5 represent the PCR products and samples in lanes 2, 4 and 6, are the digest products of each sample, respectively. Sample in lane 2 is the mutant homozygous uncut TT genotype (197 bp). Sample in lane 4 represents the wild type cut CC genotype (158 bp and 39 bp). Sample in lane 6 represents heterozygous CT genotype (197 bp, 158 bp and 39 bp).
