Use of two monoclonal antibodies in an ELISA test for the detection of antibodies to bovine leukaemia virus envelope protein gp51
Abstract
A competition ELISA technique involving two monoclonal anti-gp51 antibodies has been developed for the detection of bovine leukaemia virus (BLV) antibodies. Precoated gp51 antigen-microtitre plates were obtained by incubation of plastic adsorbed monoclonal antibody with a non-purified BLV preparation. Samples to be tested were incubated in the wells of the gp51-coated plates; the presence of anti-gp51 antibodies was indicated by competition for antigen binding with an enzyme linked monoclonal antibody directed to an important epitope on gp51. This test is as sensitive as a routinely used indirect ELISA test; it is highly specific, reliable and easy to perform.
