GFAP Antibody / Glial Fibrillary Acidic Protein

The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the GFAP antibody to be titered up or down for optimal performance.

1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 minutes.

This antibody recognizes a protein of ~50kDa which is identified as Glial Fibrillary Acidic Protein. The mAb shows no cross-reaction with other intermediate filament proteins. GFAP is specifically found in astroglia. It is a very popular marker for localizing benign astrocyte and neoplastic cells of glial origin in the central nervous system. GFAP antibody is useful in differentiating primary gliomas from metastatic lesions in the brain and for documenting astrocytic differentiation in tumors outside the CNS.
