Background
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).

I am interested in native or recombinant GFAP protein without GST Tag or in urea buffer. Can I use your GFAP antibody (NB100-53809) to detect P0809, P0810 and P1691 GFAP proteins? ..show answer..
- P0809, P0810 and P1691 are blocking peptides that are not suitable for use with NB100-53809. Unfortunately, we do not carry a GFAP protein without a GST tag. I apologize for the inconvenience.
