Anti-Glial Fibrillary Acidic Protein Antibody, clone GA5

Recommended Replacement for: CBL411
Species Reactivity Key Applications Host Format Antibody Type
H, R, M, Po, Ch, B, Rb ICC, IHC, IH(P), WB Mouse Purified Monoclonal Antibody
Anti-Glial Fibrillary Acidic Protein Antibody, clone GA5
Promotional Text:
Trade Name:
Chemicon (Millipore)
The antibody reacts with GFAP from human, pig, chicken and rat. In tissue sections this antibody stains astrocytes and Bergman glia cells (Debus, E., 1983).
Molecular Weight:
50 kDa
Purified glial filament (Debus, E., 1983).
Background Information:
Glial fibrillary acidic protein is a class-III intermediate filament. GFAP is the main constituent of intermediate filaments in astrocytes and serves as a cell specific marker that distinguishes differentiated astrocytes from other glial cells during the development of the central nervous system.
Species Reactivity:
  • Human
  • Rat
  • Mouse
  • Pig
  • Chicken
  • Bovine
  • Rabbit
Species Reactivity Note:
Human, mouse, and rat. Expected to cross-react with porcine, chicken, bovine, and rabbit.
Application Notes:
5 μg/mL of a previous lot was used.

5 µg/mL

Recognizes a 51kDa protein in reducing westerns of total brain lysates.

Entrez Gene Summary:
This gene encodes one of the major intermediate filament proteins of mature astrocytes. It is used as a marker to distinguish astrocytes from other glial cells during development. Mutations in this gene cause Alexander disease, a rare disorder of astrocytes in the central nervous system. An additional transcript variant has been described, but its full length sequence has not been determined.
UniProt Summary:
FUNCTION: SwissProt: P14136 # 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.
SIZE: 432 amino acids; 49880 Da
SUBUNIT: Isoform 3 interacts with N-terminus of PSEN1.
SUBCELLULAR LOCATION: Cytoplasm. Note=Associated with intermediate filaments.
DISEASE: SwissProt: P14136 # Defects in GFAP are a cause of Alexander disease [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.
SIMILARITY: SwissProt: P14136 ## Belongs to the intermediate filament family.
