Abstract
Objective: To construct and express a human-mouse chimeric antibody against human bladder cancer. Method: The variable region genes of anti-human bladder cancer monoclonal antibody BDI-1 were cloned by RT-PCR. A human-mouse chimeric antibody expression vector was constructed and transfected into CHO cells. The chimeric antibody against bladder cancer was expressed and characterized. Result: Eukaryotic expression vector of the chimeric antibody against human bladder carcinoma was successfully constructed, and was expressed in eukaryotic cells; the expressed chimeric antibody ch-BDI showed same specificity as its parent McAb against human bladder cancer cells. Conclusion: The constructed chimeric antibody was expressed successfully in eukaryotic cells, and the chimeric antibody had desired affinity against human bladder cancer cells.
