IHC staining of purified anti-GFAP antibody (clone Poly28294) on formalin-fixed paraffin-embedded human brain tissue. The tissue was incubated with a 1:5,000 dilution of the primary antibody for 20 minutes at room temperature. For detection, a biotinylated anti-chicken secondary was followed by the HRP labeling reagent and DAB from BioLegend's Ultra Streptavidin (USA) HRP Detection Kit (Multi-Species, DAB, Cat. No. 929901) followed by hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar: 50 µm -

Western blot of purified anti-GFAP antibody (clone Poly28294). Lane 1: Molecular weight marker; Lane 2: 20 µg of human brain lysate; Lane 3: 20 µg of mouse brain lysate; Lane 4: 20 µg of rat brain lysate. The blot was incubated with a 1:10,000 dilution of the primary antibody overnight at 4°C, followed by incubation with HRP labeled goat anti-chicken. Enhanced chemiluminescence was used as the detection system.

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.

Antigen Details
- Structure
- GFAP is a 432 amino acid protein with a molecular mass of ~50 kD.
- Distribution
-
Tissue distribution: GFAP is expressed by numerous cell types of the central nervous system (CNS) including astrocytes, ependymal cells, and Bergmann glia cells (protoplasmic astrocyte). GFAP is expressed in cells lacking fibronectin.
Cellular distribution: Cytoskeleton and cytosol Function
GFAP is a class-III intermediate filament and a structural constituent of the cytoskeleton. It is a cell-specific marker that is used to distinguish astrocytes from other glial cells during the development of the CNS. - Cell Type
