功能
GFAP, a class-III intermediate filament, is a cell-specific marker that, during the development of the central nervous system, distinguishes astrocytes from other glial cells. -
组织特异性
Expressed in cells lacking fibronectin. -
疾病相关
Defects in GFAP are a cause of Alexander disease (ALEXD) [MIM:203450]. Alexander disease is a rare disorder of the central nervous system. It is a progressive leukoencephalopathy whose hallmark is the widespread accumulation of Rosenthal fibers which are cytoplasmic inclusions in astrocytes. The most common form affects infants and young children, and is characterized by progressive failure of central myelination, usually leading to death usually within the first decade. Infants with Alexander disease develop a leukoencephalopathy with macrocephaly, seizures, and psychomotor retardation. Patients with juvenile or adult forms typically experience ataxia, bulbar signs and spasticity, and a more slowly progressive course. -

Immunofluorescence staining of GFAP using ab278054 in primary rat hippocampal mixed glia, (prepared from P2 rat hippocampal brain area, obtained from Transnetyx Tissue by BrainBits, LLC, cat.no. SDPHP4m), DIV4. The cells were fixed with 100% MeOH (5 min), permeabilized with 0.1% Triton-X-100 (in PBS) for 5 mins and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab278054 at 0.1 μg/ml and ab4674, Anti-GFAP antibody, at 1/1000 dilution. Cells were then incubated with ab150081, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed at 1/1000 dilution (shown in green) and ab150176, Goat Anti-Chicken IgY H&L (Alexa Fluor® 594) preadsorbed at 1/1000 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).
Images were acquired with the Perkin Elmer Operetta HCA and a maximum intensity projection of confocal sections is shown. The antibody ab278054 gave comparable results using 4% formaldehyde fixation (10 min).

GFAP is expressed primarily by astrocytes in the CNS as astrocytes marker. We have no suitable astrocyte for western blot testing.
U-87 MG and C6 were reported to express low level of GFAP (PMID: 23839947, PMID: 22096544, PMID: 20669222).NIH/3T3, IMR-32, HeLa and PC-12 were reported as negative cell lines for GFAP (PMID: 824020; PMID:2294; PMID: 6340792; PMID:9466565, PMID:7895062, PMID: 28700643, PMID: 19272755).
No literature was found to support the expression in SH-SY5Y, Neuro-2a and SK-N-BE (2) cell.
