Figure 1From: The promoter -1031(T/C) polymorphism in tumor necrosis factor-alpha associated with polycystic ovary syndromeThe -1031(T/C) polymorphism of the TNF-α gene. Shown is 2% agarose gel on the electrophoresis stained with ethidium bromide following Bbs I digestion. The 251- and 13-bp indicate the homozygosity of the T allele. However, 13-bp band was not observed in 2% gel. 180-, 71-, and 13-bp indicated the homozygosity of the C allele. And the T/C genotype indicates three bands of 251-, 180-, and 71-bp.Back to article page
