BAT1 -22 G/C promoter polymorphism genotyping. A representation of a typical -22 C/G genotyping gel produced after digested PCR product was run on an 8% non-denaturing PAGE gel. M = Marker (100 base pair marker – arrows represent 400, 300 and 200 bp fragments). Black arrowheads correspond to allele fragments: -22 C = 152 bp & 18 bp, and -22 G = 170 bp. Lane 1 = -22 CC genotype. Lanes 2,4,5,7,8,9,10 and 11 = -22 CG genotype. Lanes 3 and 6 = -22 GG genotype.
