title: Quantitative ELISA for human lactate dehydrogenase isoenzyme 5.
abstract: Four monoclonal antibodies (Mab) derived from mice immunized with lactate dehydrogenase 5 (LDH5) react strongly with LDH5, but weakly with LDH2 which contains a single subunit of type M. Experimental evidence suggest that these antibodies are directed to an antigenic determinant in the interface between two subunits of type M. A sandwich ELISA procedure was devised, using these Mabs to identify and quantify LDH5. The procedure involves immobilization of one of these Mabs by its adsorption onto polyclonal anti-mouse IgG coated polystyrene plates, adsorption of LDH5, its identification by the same Mab as that used in the immobilization step, and finally color development by an enzyme labeled rabbit anti-mouse IgG antiserum. The method enables LDH5 to be assayed at a concentration range of 0-5 micrograms/ml.
