Abstract

The anti-My-11 murine monoclonal antibody reported on in this work identifies a KG-1a cell surface glycoprotein with apparent molecular mass of 210,000 daltons. Peripheral blood B-lymphocytes, and a novel subset of T-lymphocytes (not coinciding with helper or cytotoxic subsets) express My-11 antigen; granulocytes, red cells, and platelets are antigen negative. In normal bone marrow, lymphoid progenitors (TdT positive) and most granulocyte-monocyte progenitors express My-11, but erythroid and multilineage progenitors are My-11 negative. Approximately half of acute leukemia blast cell specimens are My-11 positive. The My-11 antigen distinguishes between lymphohematopoietic cells on the basis of lineage, and assists in the purification of hematopoietic progenitor cells and the subclassification of leukemias and normal lymphocytes.
