GFAP Antibody / Glial Fibrillary Acidic Protein

This antibody recognizes a protein of ~50kDa which is identified as Glial Fibrillary Acidic Protein. The mAb shows no cross-reaction with other intermediate filament proteins. GFAP is specifically found in astroglia. It is a very popular marker for localizing benign astrocyte and neoplastic cells of glial origin in the central nervous system. GFAP antibody is useful in differentiating primary gliomas from metastatic lesions in the brain and for documenting astrocytic differentiation in tumors outside the CNS.
