Intermediate filaments (IFs) with characteristic 10 nm diameter are a distinct class of molecularly heterogenous cytoskeletal filaments defined by ultrastructural, immunological, and biochemical criteria. Intermediate filaments differ significantly from the other cytoskeletal elements of the cell, namely microtubules and microfilaments, and are components of most eukaryotic cells. Glial Fibrillary Acidic Protein (GFAP) (molecular weight of 50 kDa) is found in astrocytes and ependymal cells of the central nervous system. It is found in various other cell types including stellate cells, chondrocytes, osteocytes, keratinocytes, Leydig cells and fibroblasts. GFAP is involved in mitosis, and cell:cell interactions and communications. Mutations in this gene cause Alexander disease, a rare disorder of astrocytes in the central nervous system.
Rabbit polyclonal anti-Glial Fibrillary Acidic Protein recognizes human, mouse, and rat GFAPs.
synthetic peptide corresponding to an internal C-terminal sequence of human GFAP.
Rabbit polyclonal anti-GFAP antibody is used to tag glial fibrillary acidic protein for detection and quantitation by Western blotting and immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of glial fibrillary acidic protein in cell:cell communications, mitosis and cell structure. Anti-GFAP has proven a valuable tool for use in immunocytochemical localization of GFAP in normal central nervous system tissue, certain tumors and metastases of the glial antigen, as well as for immunofluorescent labeling of cultured mammalian cells.
