Abstract
We reported previously that adenocarcinoma-reactive human monoclonal antibody AE6F4, which had been generated by in vitro immunization method, recognizes both 14-3-3 protein and cytokeratin 8 (CK8). In this study, to analyze the cross-reactivity of AE6F4 antibody, epitopes of AE6F4 antibody on 14-3-3 proteins and CK8 were studied by using synthetic linear peptide scanning technology. To determine the locations of B cell epitope, 48 and 95 of decapeptides covering the entire 14-3-3 proteins and CK8, respectively, were synthesized and binding to AE6F4 antibody was examined by ELISA. The AE6F4 antibody was strongly reactive to peptides containing amino acid sequences TLWTSDTQGD in 14-3-3 proteins and INFLRQLYEE in CK8. These results indicate that AE6F4 antibody can recognize the different peptide sequences in 14-3-3 proteins and CK8.
