title: Use of monoclonal antibody in an ELISA test for the detection of antibodies to bovine leukaemia virus.
abstract: A variant of the ELISA technique, involving a monoclonal anti-gp51 antibody yields a highly sensitive method for the detection of bovine leukaemia virus (BLV) antibodies. The gp51 antigen-coated microtitre plates are obtained by incubation of plastic-adsorbed monoclonal antibodies with a non-purified mixture of BLV antigens. Sera to be tested are incubated in the wells of the gp51-coated plates and bound antibodies are revealed by an enzyme-linked antibovine immunoglobulin reagent. This test is as sensitive as liquid phase radioimmunoassay using the same gp51 antigen and thus appears as a highly sensitive, practical, rapid and cheap method for the detection of BLV antibodies.
