Glial fibrillary acidic protein (GFAP) is a class III intermediate filament (IF) protein and is used as a marker to distinguish astrocytes from other glial cells during development.
Glial Fibrillary Acidic Protein (GFAP) is one of the major intermediate filament axonal proteins found in mature astrocytes, the star-shaped glial cells that comprise the majority of cells within the central nervous system (1).
