Expression System:

Sequence :

Specificity :Recognizes the glial fibrillary acidic protein (GFAP)

Cited Applications :WB, IF

Cross Reactivity :Human, Mouse and Rat

Host / Isotype / Clone# :Rabbit, IgG

Immunogen :Recombinant and purified bovine GFAP.

Formulation :100 ul neat serum

Purification :Affinity chromatography

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Sample Data :Immunofluorescence showing specific labeling of GFAP (red) and vimentin (green) in cultured neurons and glia. Cells containing GFAP and vimentin appear yellow.

Sample Data :Western blot of rat cortex lysate showing specific immunolabeling of the ~50k GFAP protein.

Scientific Background :Glial Fibrillary Acidic Protein (GFAP) was discovered 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).
