Figure 4. Mutant 23s rRNA gene sequence chromatogram using K1K2 oligonucleotides. Sequencing traces with peaks of a fluorescent signal corresponding to peak (A) at A2143G mutation and Peak (A) at A2203G (red arrows) showed point mutations in H. pylori 23s rRNA, peak T at T2182C was not detected (green arrow)
