Genotyping of babA2 gene in Indian H. pylori isolates. The images shown are from a representative gel electrophoresis of a PCR amplification product of babA2 gene from Indian isolates and J99 control strain with A nthu_babA2F and babA2R primers [26], B babA2F and babA2R primers [20], and C babA2F and babA2R607 primers [27]. Where lane 1 positive control, lanes 2–10 clinical isolates, lane 11 negative control, and lane 12 DNA ladder
