Abstract: For expressing and preparing monoclonal antibody of CPV p32 protein,p32 gene was cloned and inserted into plasmid pET28a(+),and expressed efficiently in E.coli Rosseta by IPTG induction. After purification by affinity chromatograph,p32 protein was immunized as antigen to BALB/c mouse. 22 monoclonal antibodies which recognize recombinant p32 protein were obtained,among them,3 could recognize CPV. These monoclonal antibodies provided biomaterials for sandwich ELISA testing CPV and competitive ELISA testing CPV antibodies.

Key words: CPV; p32 gene; monoclonal antibody
