Mouse Monoclonal Antibody to GFAP

Glial fibrillary acidic protein (GFAP) is strongly and specifically expressed in astrocytes, Bergmann glia, certain other glia in the central nervous system, in satellite cells in peripheral ganglia, and in non-myelinating Schwann cells in peripheral nerves. GFAP expression is also seen in developing neural stem cells and GFAP levels may greatly increase in regions of CNS injury or disease. The formation of a GFAP rich “glial scar” following CNS injury may be one reason why reconnection of severed processes is relatively inefficient in adults. Point mutations in the GFAP gene are causative of Alexander disease (5). All forms of Alexander disease are characterized by the presence of Rosenthal fibers, which are GFAP containing cytoplasmic inclusions found in astrocytes. Some interest has recently been focused on GFAP as a protein released into blood and CSF following traumatic brain injury, stroke and other CNS compromises (6,7). Measurement of the levels of blood or CSF GFAP may give information about patient presentation, progress, response to therapy or outcome.
MCA-5C10 antibody was made against purified GFAP from porcine spinal cord, EnCor product PROT-r-GFAP. High quality antibodies to GFAP such as MCA-5C10 are useful for visualizing glia and monitoring developmental, disease and damage related CNS alterations. This antibody has been shown to work well on western blots, IF, ICC and IHC and also to recognize GFAP from a variety of species. We also supply mouse monoclonal antibodies, MCA-2A5, MCA-3E10, as well as chicken, CPCA-GFAP, rabbit, RPCA-GFAP, and goat, GPCA-GFAP polyclonal antibodies.Mouse select image at left for larger view.
This is one of a series of formalin fixed paraffin embedded adult horse brain samples generated by Maureen T. Long in the Department of Infectious Diseases and Pathology, College of Veterinary Medicine, University of Florida. The findings were recently published in the Equine Veterinary Journal, link here. The brains from this series were removed whole, sliced incompletely cross ways and fixed over a 10-20 day period. The whole brain was put in a large necropsy specimen bucket containing 1-2 gallons of fixative, and after 24 hours, the formalin was poured off and then fresh formalin was added. The samples were fixed and embedded in paraffin in 2007 and sections were kept at room temperature until 2011. The sections were processed for antigen retrieval by boiling in pH=6 Citrate buffer for 10 min. Primary incubation with MCA-5C10 was for 1 hour at 37°C, and secondary antibody incubation and color reaction was performed using the Vector mouse ABC kit. Mouse select image for larger view.
Paraffin embedded formalin fixed human cerebellum stained with MCA-5C10. The sample was processed using our standard IHC protocol outlined here. The folds of the molecular layer are at the right and granular and white matter layers are on the left. Section was lightly counterstained with hemotoxylin. Mouse select image for larger view.
