target relevance
Glial Fibrillary Acidic Protein (GFAP) is a crucial cell marker widely employed in neuroscience and neurobiology research. It is an intermediate filament protein primarily found in astrocytes, a type of glial cell in the central nervous system. GFAP serves as a reliable marker for identifying and characterizing astrocytes in various experimental models and tissues. Immunohistochemistry and immunofluorescence techniques using antibodies targeting GFAP enable researchers to visualize and quantify astrocytic populations, gaining insights into their distribution, morphology, and function in the brain. Moreover, GFAP antibodies are instrumental in studying astrocyte reactivity, a phenomenon occurring in response to brain injury or neurodegenerative diseases. As astrocytes play critical roles in neural development, neurotransmitter regulation, and maintenance of the blood-brain barrier, GFAP has proven indispensable in advancing our understanding of glial biology and its contribution to neurological disorders.

Intermediate filament family
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.
Subellular location
Cytoplasm Note=Associated with intermediate filaments.
Expressed in cells lacking fibronectin.
Interacts with SYNM. ; [Isoform 2]: Interacts with PSEN1 (via N-terminus).
Post-translational modification
Phosphorylated by PKN1.

Immunofluorescent analysis of mouse hippocampus section stained with goat pAb to GFAP, 8205, dilution 1:5,000 in green, and costained with mouse mAb to FOX3/NeuN, 2083, dilution 1:2,000, in red. The blue is Hoechst staining of nuclear DNA. Following transcardial perfusion of mouse with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45µM, and free-floating sections were stained with above antibodies. The GFAP antibody stains the network of astrocytic glial cells, while the FOX3/NeuN antibody specifically labels nuclei and proximal perikarya of neurons.
Chromogenic immunostaining of a formalin fixed paraffin embedded mouse cerebral cortex section with goat pAb to GFAP, 8205, dilution 1:10,000, detected with DAB (brown) using the Vector Elite 8718C-HRP detection and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. In normal brain tissue, the GFAP antibody specifically labels astrocytes. It can also detect chronically activated microglia in neurodegenerative conditions. Mouse select image for larger view.This antibody was raised against recombinant human GFAP expressed in and purified from E. coli. The human GFAP sequence was derived from NP_002046.1 which was inserted into the eukaryotic expression vector pET30a(+) which adds an N-terminal His tag and some other sequence which is underlined below.MHHHHHHSSG LVPRGSGMKE TAAAKFERQH MDSPDLGTDD DDKAMADIGS EFMERRRITS 60 AARRSYVSSG EMMVGGLAPG RRLGPGTRLS LARMPPPLPT RVDFSLAGAL NAGFKETRAS 120 ERAEMMELND RFASYIEKVR FLEQQNKALA AELNQLRAKE PTKLADVYQA ELRELRLRLD 180 QLTANSARLE VERDNLAQDL ATVRQKLQDE TNLRLEAENN LAAYRQEADE ATLARLDLER 240 KIESLEEEIR FLRKIHEEEV RELQEQLARQ QVHVELDVAK PDLTAALKEI RTQYEAMASS 300 NMHEAEEWYR SKFADLTDAA ARNAELLRQA KHEANDYRRQ LQSLTCDLES LRGTNESLER 360 QMREQEERHV REAASYQEAL ARLEEEGQSL KDEMARHLQE YQDLLNVKLA LDIEIATYRK 420 LLEGEENRIT IPVQTFSNLQ IRETSLDTKS VSEGHLKRNI VVKTVEMRDG EVIKESKQEH 480 KDVM 484Number of amino acids: 484Molecular weight: 55588.41Theoretical pI: 5.47Amino acid composition: Ala (A) 52 10.7% Arg (R) 49 10.1% Asn (N) 17 3.5% Asp (D) 28 5.8% Cys (C) 1 0.2% Gln (Q) 27 5.6% Glu (E) 63 13.0% Gly (G) 18 3.7% His (H) 15 3.1% Ile (I) 14 2.9% Leu (L) 58 12.0% Lys (K) 24 5.0% Met (M) 16 3.3% Phe (F) 9 1.9% Pro (P) 11 2.3% Ser (S) 28 5.8% Thr (T) 22 4.5% Trp (W) 1 0.2% Tyr (Y) 10 2.1% Val (V) 21 4.3%Total number of negatively charged residues (Asp + Glu): 91 Total number of positively charged residues (Arg + Lys): 73Ext. coefficient 20400 Abs 0.1% (=1 g/l) 0.367, assuming all pairs of Cys residues form cystinesExt. coefficient 20400 Abs 0.1% (=1 g/l) 0.367, assuming all Cys residues are reduced
Western blot analysis of brain lysates from different species using goat pAb to GFAP, 8205, dilution 1:5,000 in green: [1] protein standard (red), [2] rat cortex, [3] rat cerebellum, [4] mouse cortex, [5] mouse cerebellum, [6] cow cortex, and [7] cow cerebellum. Strong band at about 50 kDa corresponds to GFAP protein. Smaller proteolytic fragments of GFAP are also detected on the blot.
