Rabbit antisera to Abelson leukemia virus (A-MuLV)-induced murine lymphomas have been analyzed by absorption with a variety of murine lymphoma lines. Antibody binding to a panel of cell lines and normal lymphocytes was visualized by using hapten-sandwich indirect membrane immunofluorescence. Novel membrane antigens thereby detected are shared between lymphosarcomas, B lymphomas, normal B lymphocytes, and normal membrane immunoglobulin negative (sIg-) bone marrow cells, but are not found on T cells, thymic lymphomas, plasmacytoid lymphomas, or myelomas. The existence of such shared differentiation antigens suggests that sIg- A-MuLV-induced lymphosarcomas may be transformed B cell precursors. Since differences in the expression of these antigens on individual plasma-cytoid lymphoma lines were found, this category of lymphomas may include cells at a variety of differentiation states.
