Figure 1From: Single nucleotide polymorphism at alcohol dehydrogenase-1B is associated with risk of esophageal squamous cell carcinomaElectrophoresis of genomic DNA after restriction endonuclease digestion. ADH1B rs1229984 A/A allele generated one fragment of approximately 132 bp, G/G allele generated two bands of 112-bp and 20-bp, while the lanes containing both132 and 112 fragments represent the allele is A/G.Back to article page
