Abstract:
Objective:To prepare the monoclonal antibodies against chicken CARP.Methods:The chicken CARP cDNA encoding the N-terminal 110aa length of encoding region was cloned into prokaryotic expression vector pET28b.The BALB/c mice were immunized with purified the recombinant protein,spleen cells of mouse were fused with SP2/0,and the positive clones were screened by indirect ELISA.The properties of McAb were analyzed by ELISA and Western blot.Results:Two hybridomas were proved to have the capability of stably secreting McAb against chicken CARP,designated as 4A8 and 4E6,the subtype of both was IgG1,and the light chain was ?.The titers of ascites were 3.2?104 and 1.28?105 respectively.The Western blot results suggested that they could recognize chicken CARP protein.Conclusion:Two murine hybridomas secreting anti-chicken CARP McAbs have been successfully obtained.
