Restriction band pattern of G894T polymorphism in exon 7 of the NOS3 gene. Agarose gel electrophoresis of PCR products after endonuclease restriction with enzyme BannII. Lane 1, GG homozygote (163 bp and 85 bp); lane 2, GT heterozygote (248 bp, 163 bp, and 85 bp); and lane 3, TT homozygote (248 bp). M represents 50 bp ladder.
