title: [Testing of acute myeloid leukemia of humans using monoclonal antibodies BL-DR, BL-M/G, BL-T2 and BL-Ig-L/1].
abstract: The leukemic blasts of 22 patients with acute myelocytic and myelomonocytic leukemia were tested by indirect immunofluorescence with the monoclonal antibodies BL-DR (directed against HLA-DR-antigens), BL-M/G (react with both granulocytes and monocytes), BL-T2 (pan-T-lymphocyte-antibody CD 5), and BL-Ig-L/1 (anti-light-chains-antibody). The leukemic blasts showed no crossreaction with BL-DR and BL-Ig-L/1. Both the antibodies BL-DR and BL-M/G reacted mainly with the acute myelomonocytic leukemias FAB M4 and only seldom with the acute myelocytic leukemias FAB M1, M2, and M3. The antibodies BL-DR and BL-M/G are able to confirm the diagnosis of acute myelomonocytic leukemia and to classify some previously unclassifiable leukemias.
