Different recognition capacities of synthetic 11-mer CagA phosphopeptides by seven commercially available α-phosphotyrosine antibodies. The indicated phospho- and non-phospho peptides derived from single East-Asian EPIYA-motifs A, B and D of H. pylori wild-type strain TN2-GF4 were analyzed using the Dotblot method. The seven designated phosphotyrosine-specific antibodies were used as previously described [48]
