[Preparation of clenbuterol monoclonal antibody with subtractive immunization method]

To obtain Clenbuterol monoclonal antibodies.

Clenbuterol complete antigen was prepared with diazotization method. BALB/c mice was immunized with subtractive immunization, Clenbuterol monoclonal antibody was prepared with rule hybridoma technique.

The mice obtained tolerance to BSA by subtractive immunization. The rate of the hybridoma cell with positive reaction which had obtained was 8.2%, and the specific clenbuterol monoclonal antibody was obtained at last.

Monoclonal antibodies to micromolecule contaminant be prepared by subtractive immunization, could decrease the workload in the bolting of monoclonal antibodies, and increase the chance to obtain the antibody of expected.
