PCR results of dupA 1 ( long type and short type) amplified with snt49F/2499R and dupAF/2499R sets of primers in representative H. pylori strains. Lane 1 denoted 1 kb marker (NEB). Lane 2–11 showed the long type dupA1 of 2499 bp and lane 12–21 yielded the short type dupA1 of 1884 bp, lane 2, 3 and 17 did not produce any amplicon. Lanes 11 and 21 were taken as negative controls.
