Tissues were stained for S100A4 (red), beta-III-Tubulin (neuronal marker, green), and DAPI (blue) (A-B). Colocalization of S100A4 in astrocytes was evaluated by staining for S100A4 (red), GFAP (astrocyte marker, green), and DAPI (blue) (C-D). EAE = experimental autoimmune encephalomyelitis; GFAP = glial fibrillary acid protein.

GFAP Antibody in Immunohistochemistry (IHC) — Fig 1 Characterization of brain astrocytes. Astrocytes from B6 mice were isolated as described in Materials and Methods. Before use, astrocytes were stained with mAb against GFAP (green) and nuclei with DAPI (blue) followed by immunofluorescence microscopy (A, 20 magnifications) and flow cytometry (B).

GFAP Antibody in Western Blot (WB) — Figure 1 Characterization of neuronal (NDE) and astrocyte derived exosomes (ADE)s. (A) FACS analysis of plasma NDEs and ADEs following the formation of bead-antibody-exosome (BAE)--FITC complexes. Streptavidin magnetic beads were incubated with exosomes isolated from non-psychiatric comparison subjects (NC) and people with schizophrenia (PWS) ( n = 60) and enriched against biotinylated anti-human CD171 biotin (L1CAM, NDE) or anti-GLAST antibody (ADE). BAE complexes are stained with FITC prior to FACS. (B) Plasma NDE and ADE preparations from NC and PWS patients were probed with exosome marker, Flotilin-1 (1:1000). Non-exosome fraction (supernant resulting from 1 h spin at 1500G) served as the negative control while total exosomes (diluted in 1x PBS prior to neuronal and astrocyte enrichment) served as the positive control. The resultant Western Blot demonstrated that NDEs are Flotillin and Neun positive and GFAP negative. However, we were not able to get a signal for the ADEs. Due to multiple freeze-thaw cycles, the integrity of the samples used in the current study had diminished significantly.

GFAP Antibody in Flow Cytometry (Flow) — Figure 5. Depletion of microglia enhanced astrocyte response after brain ischemia. C57BL/6 mice were fed with PLX3397 or control diet for 21 days prior to MCAO. At 24 h after ischemia and reperfusion, single cell suspensions were prepared from brain or spleen tissues of MCAO mice receiving PLX3397 or control diet. (a) Representative flow cytometry plots and bar graph show astrocytes (GFAP + ) in MCAO mice receiving PLX3397 or control diet, at 24 h after ischemia and reperfusion. (b)-(c) Representative plots (b) and bar graphs (c) of flow cytometry analysis show the expression of IL-1alpha, IL-1beta, iNOS, CCL2, TNF-alpha, IL-6 in astrocytes obtained at 24 h after MCAO from mice receiving PLX3397 or control diet. n = 15 mice per group.

Product Specific Information

Description: This GA5 monoclonal antibody reacts with human, mouse, rat, chicken, rabbit, and pig glial fibrillary acidic protein (GFAP). This 49-kDa type III intermediate filament protein is expressed in neural tissues and distinguishes astrocytes from other glial cells during central nervous system development. Three alternative splice variants of GFAP exist; however, alpha-GFAP is the predominant form expressed in astrocytes. GFAP can co-assemble with vimentin and nestin in astrocytes, but such associations are not required for assembly. Like other intermediate filaments, GFAP assembly is dependent on phosphorylation and dephosphorylation of the N-terminal domain. Studies have demonstrated that mutations in the GFAP gene lead to Alexander disease. Moreover, GFAP has also been shown to be overexpressed in certain glial-derived tumors.

Applications Reported: This GA5 antibody has been reported for use in intracellular staining followed by flow cytometric analysis, immunohistochemical staining of frozen and formalin-fixed paraffin embedded tissue sections, and immunocytochemistry.

Applications Tested: This GA5 antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded human tissue using low pH antigen retrieval and can be used at less than or equal to 10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

eFluor® 660 is a replacement for Alexa Fluor® 647. eFluor® 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.

Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser.

Filtration: 0.2 µm post-manufacturing filtered.

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 of the central nervous system, in satellite cells of peripheral ganglia, and in non-myelinating Schwann cells of 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.
