Abstract: To develop and characterize monoclonal antibody (McAb) against porcine reproductive and respiratory syndrome virus NVDC-JXA1 strain (PRRSV NVDC-JXA1 strain) for related research work.BALB/c mice were immunized conventionally with the purified virions of PRRSV NVDC-JXA1 strain.On the third day after the final immunization,spleen cells of mice fused with myeloma cells SP2/0 were filtered by culturing selectively,diluting finitely,enzyme-linked immunosorbent assay (ELISA) and IFA test,to obtain the subtypes from the clone line by ELISA test.As a result,the cell lines secreted McAbs stably by culturing in vitro and recovery tests were obtained and named as 1D12,5H5 respectively,the ELISA titers of ascites was 1∶107,1∶105 respectively.The subtypes of the two McAbs were identified as IgG2b and IgM,Kappa light chain.The two McAbs reacted specifically with only matrix protein of PRRSV but not with PRV,PPV,PCV,CSFV,JEV by indirect-ELISA.The McAbs will be very useful as specific reagents in diagnosis and control of PRRS.
