Whiteley Date Approved: Feb. 6, 2009 Date Modified: 1. PURPOSE This procedure is to be used for the characterization of purified monoclonal antibody. 2. SCOPE This document describes the procedure for the indirect Enzyme Linked ImmunoSorbant Assay (ELISA) that is used to assess the reactivity of the monoclonal antibodies for the recombinant antigens used as immunogens. It is not intended as a procedure for measurement of native antigens. It is also not to be used as the procedure for assessment of reactivity in unpurified monoclonal antibodies. 3. RESPONSIBILITIES It is the responsibility of the person(s) performing this test to be familiar with lab safety procedures and to have basic laboratory skills. The interpretation of the results must be done by a person trained in the procedure and familiar with such interpretation. 4.
