Figure 2: Agarose gel electrophoresis of genomic PCR for GSTT1 and β-globin. M, high-molecular-weight marker. Positive GSTT1 and β-globin alleles yielded 480 and 268 bp products, respectively, against DNA ladder 100 bp (100 bp for each band). The absence of the 480 bp band indicates the GSTT1 null genotype (OO) (lanes 3 and 5). Thick 480 bp bands indicate the normal GSTT1 genotype (TT) (lanes 1, 6, and 7) and the presence of a thin band of 480 bp indicates the heterogeneous GSTT1 genotype (TO) (lanes 2 and 4). GSTT1, glutathione S-transferase T1.
