Figure 1.
Representative gel pictures of 27-base pair (bp) variable number of tandem repeats of endothelial nitric oxide synthase (eNOS), inducible NOS (iNOS)22 G/A (rs1060826), and neuronal NOS (nNOS) C/T (rs2682826) polymorphisms. (A) Polymerase chain reaction (PCR) products of 27-bp VNTR of eNOS polymorphism were run on 3% agarose gel electrophoresis (AGE): lanes 2–7 show various genotypes, lane 1 shows a 50-bp DNA ladder. (B) PCR-restriction fragment length polymorphism products of iNOS22 G/A (rs1060826) polymorphism were run on 3% AGE: lanes 2–7 show various genotypes, lane 1 shows a 50-bp DNA ladder. (C) PCR-restriction fragment length polymorphism products of nNOS C/T (rs2682826) polymorphism were run on 15% polyacrylamide gel electrophoresis (PAGE): lanes 1–3 and 5–6 show various genotypes, lane 4 show a 50-bp DNA ladder.
