title: Antigens of monoclonal antibody NB3C4 are novel markers for oligodendrocytes.
abstract: We produced NB3C4, a novel monoclonal antibody specific for oligodendrocytes, using human neuroblastoma IMR-32 cells. NB3C4 specifically recognized oligodendrocytes in the CNS, although it bound to neuroblastoma IMR-32 cells and oligodendrocytes in vitro. Double immunofluorescence staining of rat brain using NB3C4 and anti-GST-pi, anti-glial fibrillary acidic protein (GFAP), or anti-neurofilament 200 (NF) antibody revealed that anti-GST-pi antibody identified an oligodendrocyte marker recognizing NB3C4-positive cells, while both anti-GFAP and anti-NF antibody did not. Western blotting of rat brain homogenates showed that NB3C4 bound three proteins of 22-28 kDa, while the anti-GST-pi recognized a 27 kDa protein. Therefore, antigens recognized by NB3C4 could be novel markers for oligodendrocytes.
