Research Abstract

Monoclonal antibody technology makes if possible to analyse specific and crossreacting antigens among strains of a single bacteral or viral species, and could be used for immunodiagnosis.
One hybride secreting antibldy (C-1) to the VR-299 serotype of infectious pancreatic necrosis virus (IPNV) was selected from the fusion of myeloma cells and spleen cells from mice immunized with pelleted virus. The C-1 monoclonal antibody possessed the kappa (K) light chain isotype and had the gamma 1. (G1). C-1 monoclonal antibody showed the ability to neutralize the VR-299 serotype of IPNV. Using a fluorescent antibldy technique (FAT) and coagglutination test, C-1 monoclonal antibody was found to be broadly reactive against the representative three serotypes of IPNV, VR-299, Ab and Sp strains. By the radioimmunoprecipitation (RIP) and western blotting method, C-1 monoclonal antibody was reacted only with <beta> protein of IPNV induced polypeptide and structural polypeptide of virus virion.
C-1 monoclonal antibody could be used for the rappid diagnosis of IPN using the FAT and coagglutination test. C-1 monoclonal antibody sensitized staphylococci showed positive reaction with the filtrate antigen prepared from diseased fish within 30 min.
For other fish pathogens, 6 hybrids which produced the antibody against the A. salmonicida were established and the culture medium of these hybrids showed the reaction with only the homologous antigen by FAT.
