Oligodendrocyte cell surface recognized by a novel monoclonal antibody specific to sulfatide.
A rat monoclonal antibody (OL-1) was obtained by in-vitro immunization of rat spleenocytes with paraformaldehyde-fixed primary cultured glial cells derived from newborn rat brain and subsequent fusion with a rat myeloma cell line. The antibody secreted by the hybridoma immunostains live rat and mouse oligodendrocytes in primary and secondary cultures. The antibody binds specifically to oligodendrocytes and myelin structures in-situ. Radioimmunolabelling assays with a number of purified glycolipids offer thin layer chromatography separation show that OL-1 antibody binds strongly to sulfatide and to a lesser extent to galactosyl diglyceride.
