Production of mouse monoclonal antibodies against Helicobacter pylori Catalase and mapping the antigenic epitope by phage display library
چکیده انگلیسی

SummaryThe Catalase of Helicobacter pylori (H. pylori) helps bacteria to protect themselves from oxygen toxicity and damage and have been identified an immunodominant antigen. To obtain mouse monoclonal antibodies (mAbs) against Catalase and to map its antigenic epitope is potentially to develop a vaccine for prevention and treatment of H. pylori infection. In our study, MAbs were produced by the hybridoma technique using recombinant Catalase–GST as the immunogen and were immunoscreened against phage-displayed random dodecapeptide library (Ph.D.-12). After three rounds of biopanning, 34 phage clones were randomly selected and their specificity to mAb was verified by sandwich and competitive inhibition ELISA. Fifteen phage clones were sequenced and their amino acids were deduced. One mimotope (SVSLPYANLATH) showed good match with Catalase protein at 394–405aa and the serum of mice induced by the phage clone clearly recognized Catalase protein. Our work suggests that the antigenic epitope could be mapped through screening the phage-displayed peptide libraries with mAb and a mimotope of Catalase would provide an alternative approach for the development of a vaccine for H. pylori.
