PCR amplification using the dupA multiplex PCR. (A)Genomic DNA from H. pylori strains J99 (positive control), 26695 (negative control) and FD527 (clinical isolate) were used to PCR amplify dupA using the forward primers dupA113 F and dupA 1274F, and the reverse primers dupA 1083R, dupA 1674R and dupA 1830R. M, size markers (in base pairs). (B) Schematic representation of dupA showing the annealing positions of the forward primers dupA113 F and dupA 1274F, and the reverse primers dupA 1083R, dupA 1674R and dupA 1830R, and the expected sizes of the amplified PCR products.
