摘要: The monoclonal antibody ID11D7 to carboxypeptidase A (CPA) was prepared. The inhibitory effect of McAb ID11D7 on the peptidase activity of CPA was measured. The result reflects that the McAb ID11D7 can competitively inhibit the peptidase activity of CPA with an apparent inhibitory constant of 6.3 × 10-9M. Based on this work, the McAb ID11D7 can be used as idiotypic antigen to prepare anti-idiotypic catalytic antibody with the peptidase activity similar to CPA.
