Polymorphisms of the TLR2 and TLR4 genes are associated with risk of gastric cancer in a Brazilian population

Figure 1 Eletrophoretic pattern of fragments generated by polymerase chain reaction-allele specific and polymerase chain reaction-restriction fragment length polymorphism for the polymorphisms. A: Toll-like receptor (TLR)2 -196 to -174 del: ins/ins = 286 bp; ins/del = 286 + 264 bp; del/del = 264 bp; B: TLR4 + 896A/G: A/A = 131 bp; A/G = 131 + 108 bp and positive control of enzyme BstXI, TLR2 gene fragment of 286 bp with the enzyme cutting site: 188 + 98 bp (last lane); C: TLR4 + 1196 C/T: C/C = 407 bp; C/T: 407 + 378 bp and positive control of enzyme HinfI, interleukin-1β gene fragment of 370 bp with the enzyme cutting site: 195 + 175 bp (last lane). M: Molecular weight marker of 100 bp.
