Objectives: The ureB subunit of urease is a major target recognized by the antibodies of Helicobacter pylori-infected patients. The minimal epitope was determined to be an 8-mer peptide (H-SIKEDVQF-OH).
Design And Methods: The aim of this study was to discover whether this synthetic 8-mer peptide (BK-61A) directly recognizes the anti-ureB subunit antibodies of H.
