title: Production and characterization of high affinity monoclonal antibodies to cyclic anti-depressant molecules.
abstract: A procedure is reported by which high levels of the tricyclic molecule desipramine was modified and conjugated at high density to the carrier molecules keyhole limpet hemocyanin and bovine serum albumin so that these could be used as immunogens in Balb/c mice. Such conjugates generated immune responses with high levels of antibody with specificity for the tricyclic. B cell hybridomas generated by fusion of immune Balb/c splenocytes to NS-1 cells which secreted monoclonal antibodies with specificity for the tricyclic were selected in a standard ELISA. In this report, we show that the binding constants of these monoclonal antibodies with various haptens can be assessed accurately by measuring fluorescence polarization, that a high degree of cross-reactivity between the monoclonals and various tricyclics exists, and that this procedure can be used to generate monoclonal antibodies of high binding constants.
