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.
This antibody was made against a recombinant construct containing amino acids 71-217 of the human isotype 1 sequence in NP_002046.1. This region is somewhat variable between species so antibodies to this human construct may be superior on human cells, tissues and for biomarker assays of human proteins. MO22205 has a KD of 6.157 X 10-10M. High quality antibodies to GFAP, like MO22205, are useful for visualizing glia and monitoring developmental, disease and damage related CNS alterations and for ELISA and bead based type assays.
