Synthesized Rb peptide was used as an antigen to immunize the BALB/C mice. After fusing and screening with ELISA and Western Blot, we got 3 hybridomas which secreted specific monoclonal antibodies against product of Rb gene. All of three kinds of antibodies were fourld to be IgG 1 through the appraisement. In addition,since we mixed three kinds of peptides as the antigens to immunize the mice,we have got three different hinds of monoclonal antibodies including one against Rb product and another two in the Same procedure.
