Mouse hybridomas producing antibodies against structural proteins of canine distemper virus (CDV) were produced by fusion of Sp2/0 myeloma cells with spleen cells from BALB/c mice immunized with purified preparations of Vero cell-grown CDV. Ascites fluids collected after intraperitoneal inoculation with 149 CDV antibody-producing hybridoma cell lines were characterized by different serological ...

The protein of human serum, tentatively designated beta(1C)-globulin, was shown to possess serological activity and to be related to the complement system. Another serum protein (beta(1A)-globulin) was identified as the inactivated form of beta(1C)-globulin. Incubation of fresh serum with various immune precipitates or with soluble gamma-globulin aggregates at 37 degrees C. resulted in the remo...
