Helicobacter Pylori Variants with ABC-Type Tyrosine Phosphorylation Motif in Gastric Biopsies of Ghanaian Patients

Figure 2

Detection of cagA gene 3-end variable sequence in Ghanaian isolates. Representative ethidium bromide-stained 2.5% agarose gel electropherogram of multiplex PCR for the identification of the H. pylori cagA 3 variable end sequence.  bp molecular weight ladder; lanes 3 and 5: amplification of a single variable sequence of cagA gene of H. pylori strain with band size of 285 bp, and  bp. Lanes 1, 2, and 4: amplification of double variable sequences of cagA gene with band sizes 207 bp and 285 bp; lane PC: positive control DNA of H. pylori strain (ATCC 43504) showing three cagA gene 3-end variable sequences (ABCCC); NC: negative control.
