This antibody reacts with GFAP. In the central nervous system, this antibody stains Astrocytes and some groups of Ependymal cells. However, in the peripheral nervous system, it stains Schwann cells, satellite cells and enteric glial cells. Cellular localization: Cytoplasmic.

Glial fibrillary acidic protein (GFAP) is a member of the class III intermediate filament protein family. It is heavily, and specifically, expressed in astrocytes and certain other astroglia in the central nervous system, in satellite cells in peripheral ganglia, and in non myelinating Schwann cells in peripheral nerves. In addition, neural stem cells frequently strongly express GFAP. Antibodies to GFAP are therefore very useful as markers of astrocytic cells. In addition many types of brain tumor, presumably derived from astrocytic cells, heavily express GFAP. GFAP is also found in the lens epithelium, Kupffer cells of the liver, in some cells in salivary tumors and has been reported in erythrocytes.Synonyms: Glial Fibrillary Acidic Protein
