Specificity
This monoclonal antibody recognizes a protein of ~50kDa which is identified as Glial Fibrillary Acidic Protein (GFAP). It shows no cross-reaction with other intermediate filament proteins. GFAP is specifically found in astroglia. GFAP is a very popular marker for localizing benign astrocyte and neoplastic cells of glial origin in the central nervous system. Antibody to GFAP is useful in differentiating primary gliomas from metastatic lesions in the brain and for documenting astrocytic differentiation in tumors outside the CNS.

Background: GFAP
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).
