title: Characterization of seven new monoclonal antibodies against human DR, DR + DP and DQ1 + DQ3 antigens.
abstract: Seven murine monoclonal antibodies were prepared that react with human class II antigens. Four of them (HL-39, MEM-12, MEM-24G, and MEM-32B: react with a monomorphic determinant dependent on association of heavy and light chains of DR antigens, two others (HL-38 and HL-40) recognize a monomorphic determinant localized on the light chains of DR and DP antigens. The antibody HL-37 is directed against a determinant present on DQ1 and DQ3, but not DQ2 molecules; at least in the case of DQ1, the epitope recognized is located on the light chain.
