Scientific Data Images for GFAP Antibody (5C10)

Immunohistochemistry Free-Floating: GFAP Antibody (5C10) [NBP1-05197] - Analysis of rat cerebellum section stained with mouse GFAP mAb, dilution 1:1,000 (Green), costained with rabbit neurofilament NF-L pAb, dilution 1:2,000 (Red). Following transcardial perfusion with 4% paraformaldehyde, brain was post fixed for 24hrs, cut to 45uM, and free-floating sections were stained with antibodies. The GFAP antibody stains a network of astroglial cells, while the NF-L antibody labels neuronal cells and their processes.
Simple Western: GFAP Antibody (5C10) [NBP1-05197] - Simple Western lane view shows a specific band for GFAP in 0.05 mg/ml of Human Brain lysate. This experiment was performed under reducing conditions using the 12-230 kDa separation system.
Immunohistochemistry: GFAP Antibody (5C10) [NBP1-05197] - The immunofluorescence of TLR7 recognized by Alexa 488, green (NBP2-24906). GFAP recognized by Alexa 594, red. NEUN recognized by Alexa 633, (blue) and merged image in the hippocampal region. NeuN and GFAP were applied to show the distribution of TLR7 within neuronal and supportive tissue populations.

Background: GFAP

Glial fibrillary acidic protein (GFAP) is a class III intermediate filament protein that is largely expressed in astrocytes in addition to non-myelinating Schwann cells and glial cells (1,2). Other members of the type III intermediate filament family include desmin, peripherin, and vimentin (2-4). GFAP was first identified in the brains of multiple sclerosis patients (2). Human GFAP protein is 432 amino acids in length with a theoretical molecular weight of ~50 kDa (1,3). GFAP has at least 10 known isoforms, with the most prevalent and common in the brain being GFAP-alpha which is made of a head domain, a rod domain with four coils (1A, 1B, 2A, 2B) joined by linker regions, and a tail domain (1). GFAP is a marker of mature astrocytes, but is also expressed throughout development in both fetal and adult neural stem cells (2). While the exact function of GFAP is still elusive, it has been shown to play a role in cellular processes such as migration, mitosis, structural integrity, and signaling (2).

An increase in GFAP levels is often associated with neuroinflammation which results in the activation and proliferation of astroglia cell population (1,2). GFAP expression is also observed in brains of patients with neurodegenerative diseases including Alzheimer's and Parkinson's, epilepsy disorders, and brain injuries (1-4). Lesion sites associated with neurodegeneration can exhibit an array of gliosis characteristics from glial scarring with reduced astrocyte proliferation to activated, GFAP-positive astrocytes surrounding amyloid plaques (2). Furthermore, the GFAP gene is a target of single nucleotide polymorphisms in the coding region, considered a gain-of-function mutation, characterized by astrocytic inclusions, termed Rosenthal fibers, resulting in Alexander Disease (1-4). GFAP is also a center of many post-translational modifications, such as phosphorylation, which can alter various aspects of filament assembly (1,4).
