title: MBM-1, a differentiation marker of mouse hemopoietic cells defined by a rat monoclonal antibody.
abstract: Hybridoma clones were isolated after the fusion of mouse myeloma cells with spleen cells from a rat immunized with mouse bone marrow. One of them produced a monoclonal antibody reacting with a murine cell surface differentiation antigen that we have termed MBM-1 (Mouse Bone Marrow-1). This antigen is present on eosinophils, on neutrophils, and on subpopulations of lymphocytes and macrophages, but appears to be absent from erythroid cells. Precursor cell analysis, after sorting of bone marrow cells using a fluorescence-activated cell sorter, suggests that the antigen is absent from most progenitors with the exception of certain cells in the macrophage lineage.
