Glial fibrillary acidic protein (GFAP) is the 10nm or intermediate filament protein found specifically in astrocytic cells in the central nervous system. Antibodies to GFAP are therefore widely used to identify astrocytic cells in situ and in tissue culture. This antibody was developed using bovine spinal cord GFAP purified from a Triton X-100 extract of myelin associated material and further purified by centrifugation and ion exchange chromatography in 6m urea on DEAE cellulose.
