Fig. 1From: Role of advanced glycation end products and sorbitol dehydrogenase in the pathogenesis of diabetic retinopathyGenotypes of the C/G polymorphism at the – 1214-bp SDH promoter region determined by allele-specific PCR detection (ASO-PCR) and analyzed by 2% agarose gel electrophoresis, stained with ethidium bromide, and viewed under gel documentation system. Lane M is the (100 bp) DNA ladder; lanes 1–4 show the result of amplification with primer specific to the G allele at 494 bp and lanes 5–8 with primer specific to the C alleleBack to article page
