Description |
GFAP is a 50 kDa intra-cytoplasmic filamentous protein of the cytoskeleton in astrocytes. During the development of the central nervous system, it is a cell-specific marker that distinguishes astrocytes from other glial cells. GFAP immunoreactivity has been shown in immature oligodendrocytes, epiglottic cartilage, pituicytes, papillary meningiomas, myoepithelial cells of the breast and in non-CNS: Schwann cells, salivary gland neoplasms, enteric glia cells, and metastasizing renal carcinomas. |

Mouse |
Applications |
Western Blotting (WB), Immunocytochemistry (ICC) and Immunohistochemistry (IHC). A dilution of 1:5,000 is recommended for WB. Human GFAP has a predicted length of 432 residues and a MW of 50 kDa. A dilution of 1:500-1:1,000 is recommended for ICC/IHC. This antibody works well on frozen sections, cells in tissue culture and on formalin fixed histological sections. Biosensis recommends optimal dilutions/concentrations should be determined by the end user. |
Specificity |
The specificity of this antibody has been confirmed by WB. |
Antibody Against |
Glial Fibrillary Acidic Protein |
Cross-reactivity |
Human, Rat, Mouse, Bovine, Porcine. Predicted to react with other mammalian and avian species. |

Mixed neuron-glial cultures stained with Mouse monoclonal antibody to Glial Fibrillary Acidic Protein [5C10] M-1375-100 (red) and chicken polylclonal antibody to neurofilament L C-1390-50 (green). The GFAP antibody stains the network of astrocytes in these cultures, while the NF-L antibody stains neurons and their processes. The blue channel shows the localization of DNA. |

IHC Method: Following transcardial perfusion with 4% PFA, brain was post-fixed for 24 hours, cut to 45 um sections, and free-floating sections were stained. Clone 5C10 stains a network of astroglial cells, while the NF-L antibody labels neuronal cells and their processes.
