[Radioimmunologic detection of antibodies to bovine leukemia virus]
The radioimmunologic assay (RIA) was elaborated for a demonstration of serum antibodies to bovine leukosis virus. The procedure makes use of the viral antigen bond to the fixed phase of a polystyrene carrier. The method was compared with the ELISA method and pseudoneutralizing and immunodiffusion tests. High congruence of the results of the RIA and ELISA methods was achieved, making 95%. The RIA method is more sensitive than the immunodiffusion test.
