Product Type Specific: GFAP cytoskeletal protein pan-specific antibody
Antibody Code: NN260-3
Antibody Target Type: Pan-specific
Protein UniProt: P14136
Protein SigNET: GFAP
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Synthetic peptide patterned after human GFAP
Antibody Immunogen Sequence: CGEVIKESKQEHKDVM-cooh
Antibody Immunogen Description: Corresponds to amino acid residues G418 to M432.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: The 50 kDa type III intermediate filament protein glial fibrillary acidic protein (GFAP) is a major structural component of astrocytes. It features a central rod domain, an amino-terminal head, and a carboxyterminal tail. GFAP associates with the calcium binding protein annexin II-p2 and S-100. Association with these proteins together with phosphorylation regulates GFAP polymerization. Astroycytes respond to brain injury by proliferatin (astrogliosis), and one of the first events to occur during astrocyte proiliferation is increased GFAP expression. GFAP regulates astrocyte motility, shape, and structure, contributing to the cytoskeleton. It also plays a role in astrocyte reactivity, responding to CNS injury. It is mainly found in astrocytes and ependymal cells in the brain and spinal cord, but it is also expressed in some peripheral tissues, such as Leydig cells in the testis and some cells in the kidney. Antibodies to GFAP have been detected in individuals with dementia. GFAP is highly upregulated in response to injury (e.g., ischemia, trauma) and neurological diseases, such as Alzheimer's Disease and NMOSD.
