Additional file 2: Figure S2. of Toll-like receptors genes polymorphisms and the occurrence of HCMV infection among pregnant women

a and b Representative chromatograms of DNA fragments of various sequenced PCR products, encompassing TLR2 2258 G > A (A, B), TLR4 896 A > G (C, D), TLR4 1196 C > T (E, F) and TLR9 2848 G > A (G-I) SNPs. For TLR2 SNP, DNA forward strands were sequenced, and for TLR4 and TLR9—reverse strands were assayed. The numbers above some peaks of chromatograms indicate the following nucleotides determined in sequenced DNA fragments. Loci of the polymorphisms and genotypes analyzed in the study, are indicated with arrows. GG, GA, AA, AG, CT, CC—genotypes determined in studied TLR SNPs. (ZIP 1732 kb
