Abstract
A set of three monoclonal antibodies (MoAbs), ED1, ED2, and ED3, has been shown to recognize in situ different subsets of macrophages in the rat. This macrophage diversity can be correlated with differences in stage of differentiation of cells belonging to one lineage. The present study quantifies this antigen distribution in the macrophage fractions of several lymphoid organs provided by Percoll centrifugation. Four new MoAbs (ED4, ED7, ED8, and ED9) raised against macrophages are included in this study. The tissue distribution of each of the four new MoAbs is determined by immuno- and enzyme-histochemistry on cryostat sections. The MoAbs recognize distinct subpopulations of macrophages. The new MoAbs ED4, ED7, ED8, and ED9 recognize granulocytes and other unrelated cell types, as well as cells of the mononuclear phagocyte system. ED7 and ED8 recognize a surface heterodimer of Mr 160,000 and 95,000.
