Description: Glial fibrillary acidic protein (GFAP) is an intermediate filament protein of 52kD found in glial cells such as astrocytes and ependymal cells. In the peripheral nervous system, GFAP has been demonstrated in Schwann cells, enteric glial cells and satellite cells of human sensory ganglia. In neoplastic tissues, this antibody is useful for the identification of astrocytomas and ependymomas.
