All GFAP Glial fibrillary acidic protein antibodies

GFAP is a protein that is expressed in astrocytes and is commonly used as a specific marker to differentiate astrocytes from other glial cells. Through a cell-based assay (CBA) and/or a tissue-based assay (TBA), specific immunoglobulin (Ig)G autoantibodies that selectively target GFAP in astrocytes have been detected in the serum and the cerebrospinal fluid of patients with autoimmune GFAP astrocytopathy (GFAP-A). GFAP autoantibody, especially IgG that binds to GFAPα, has been reported in the cerebrospinal fluid (CSF) and serum of patients with GFAP astrocytopathy.
