Description of Target:
Glial Fibrillary Acidic Protein (GFAP) was discovered by Amico Bignami and co-workers as a major fibrous protein of multiple sclerosis plaques (1). It was subsequently found to be a member of the 10nm or intermediate filament (IF) family, specifically the IF family Class III, which also includes peripherin, desmin and vimentin. GFAP is strongly and specifically expressed in astrocytes and certain other astroglia in the CNS, in satellite cells, peripheral ganglia, and in non-myelinating Schwann cells in peripheral nerves. In many damage and disease states GFAP expression is heavily upregulated in astrocytes. In addition, neural stem cells frequently strongly express GFAP. Point mutations in the protein coding region of the GFAP gene lead to Alexander disease which is characterized by the presence of abnormal astrocytes containing GFAP protein aggregates known as Rosenthal fibers (2).
Molecular Weight:
Total IgY fraction.
Tissue Tool:
Find tissues and cell lines supported by DNA array analysis to express GFAP.
RNA Seq:
Find tissues and cell lines supported by DNA array analysis to express GFAP.
Recombinant and purified bovine GFAP.
Predicted Homology Based on Immunogen Sequence:
Human; Mouse; Rat
Printable datasheet for OAPC00115
Specific for the ~50kDa GFAP protein. A lower band at ~45kDa is a proteolytic fragment derived from the GFAP molecule.
Application Info:
The antibody has been directly tested for reactivity in human, mouse and rat. It is expected that the antibody will react with other mammalian tissues.
