Helicobacter pylori Is Not Eradicated after Triple Therapy: A Nested PCR Based Study

Figure 5

Electrophotograph of restriction analysis of ureC (glmM) gene of H. pylori strains with Hind III, restricted 882 bp ureC gene amplicon into 3 fragments (435, 303, and 144 bp). Lanes 1, 18, 19, and 36: 100 bp molecular marker; lanes 2 to 17: restriction pattern of PCR product specific to ureC before treatment; lanes 20–35: restriction pattern of amplicons specific to ureC gene after treatment.
