Figure 1From: Concurrent genotyping of Helicobacter pylorivirulence genes and human cytokine SNP sites using whole genome amplified DNA derived from minute amounts of gastric biopsy specimen DNAVacA -primers. Schematic representation of the approximate location of the vacA-primers used in the present study (Table 2). SS = signal sequence region; ATR = amino-terminal region; MR = middle-region; CTR = Carboxyterminal region (nomenclature adapted from [50]).Back to article page
