GFAP Antibody — Published figure using GFAP monoclonal antibody (Product # MA5-12023)

GFAP Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of beta-3 Tubulin (green) and GFAP (red) in human iPSC-derived forebrain organoids derived at Day 84. The organoids were fixed with 4% PFA for 1 hour at room temperature, followed by incubation with 30% sucrose solution overnight at 4°C. The organoids were then embedded in OCT and cryosectioned at 5 µm, permeabilized with 0.2% Triton X-100 for 20 min, and blocked with 10% donkey serum in PBS for 30 min at room temperature. Organoid slices were stained with a Mouse beta-3 Tubulin monoclonal antibody (green; Product # MA1-118) at a dilution of 1:500, and a Rat GFAP monoclonal antibody (red; Product # 13-0300) at a dilution of 1:500 in blocking buffer overnight at 4°C, and then incubated with Donkey anti-Mouse Alexa Fluor 488 (Product # R37114) and Donkey anti-Rat Alexa Fluor 568 (Product # A11077) at a dilution of 1:1000 as well as DAPI (blue; 1:25000) in blocking solution at room temperature for 1 hour. Images were takenat 20X magnification. Data courtesy of Dr. Zhexing Wen at Emory University.

GFAP Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemistry analysis of GFAP showing staining in the cytoplasm of paraffin-embedded human cerebellum tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a GFAP monoclonal antibody (Product # MA5-12023) diluted in 3% BSA-PBS at a dilution of 1:200 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

GFAP Antibody in Immunohistochemistry (IHC) — Formalin-fixed, paraffin-embedded human brain stained with GFAP antibody using peroxidase-conjugate and DAB chromogen. Note cytoplasmic staining of astrocytes.

GFAP Antibody in Western Blot (WB) — Western blot of Glial Fibrillary Acidic Protein using Glial Fibrillary Acidic Protein Monoclonal Antibody (Product # MA5-12023) on IMR-5 Cells.

Product Specific Information

MA5-12023 targets Glial Fibrillary Acidic Protein in IF, IHC (P), and WB applications and shows reactivity with Chicken, Human, Porcine, and Rat samples.

The MA5-12023 immunogen is glial Fibrillary Acidic Protein.

MA5-12023 was successfully used to detect astrocytes in E18 Sparague Dawley primary cortical cells.

Target Information

GFAP (Glial fibrillary acidic protein) is a member of the class III intermediate filament protein family. GFAP is heavily, and specifically, expressed in astrocytes and certain 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 strongly express GFAP. Antibodies to GFAP are 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. GFAP is used as a marker to distinguish astrocytes from other glial cells during development. Mutations in this gene cause Alexander disease, a rare disorder of astrocytes in the central nervous system. Alternative splicing of the GFAP gene results in multiple transcript variants encoding distinct isoforms.
