title: The use of monoclonal antibodies raised against a human IgE myeloma paraprotein for the study of allergen extracts and sera from allergic patients.
abstract: Murine monoclonal antibodies have been produced against a single human IgE myeloma preparation. A single fusion yielded six different monoclonal antibodies which bound strongly to the immunogen. Two of these failed to react with 'normal' human IgE or with a second IgE paraprotein. The other four antibodies reacted with normal and myeloma-derived IgE and were found to be specific for antibodies of this class. Two of these antibodies were potent reagents for the detection of IgE by two site immunoradiometric assay, immunoblotting, and radioallergosorbent test. The other two antibodies were considerably less potent reagents when used in these assay systems. Our findings suggest that care should be taken in selection of suitable monoclonal antibodies for immunochemical study of allergens and sera from allergic patients.
