Fig. 2From: A study of the genotyping and vascular endothelial growth factor polymorphism differences in diabetic and diabetic retinopathy patientsDigestion products for − 152 G > A VEGF polymorphism by Ddel restriction enzyme, samples was electrophoresed on a 2% agarose gel. Lane M represents ladder 100 bp. Lanes 1, 2, 3, 4, 5 represent AA mutant genotype (one band at 204 bp)Back to article page
