| 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.

| Protein names Glial fibrillary acidic protein (GFAP) |
| Gene names GFAP,GFAP |
| Protein family Intermediate filament family |
| Mass 49880Da |
| Function 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. |
| Tissues Expressed in cells lacking fibronectin. |
| Structure Interacts with SYNM. ; [Isoform 2]: Interacts with PSEN1 (via N-terminus). |
| Post-translational modification Phosphorylated by PKN1. |
| Involvement in disease Alexander disease (ALXDRD) [MIM:203450]: A rare disorder of the central nervous system. The most common form affects infants and young children, and is characterized by progressive failure of central myelination, usually leading to death within the first decade. Infants with Alexander disease develop a leukodystrophy 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. Histologically, Alexander disease is characterized by Rosenthal fibers, homogeneous eosinophilic inclusions in astrocytes. Note=The disease is caused by variants affecting the gene represented in this entry. |

Data
 |
| Immunofluorescent analysis of a rat cerebellum section stained with rabbit pAb to GFAP, 2539, dilution 1:5,000 in green and costained with mouse mAb to MeCP2 dilution 1:500, in red. The blue is Hoechst staining of nuclear DNA. Following transcardial perfusion of rat with 4% paraformaldehyde, brain was post fixed for 1 hour, cut to 45µM, and free-floating sections were stained with above antibodies. The GFAP antibody stains the network of astrocytic cells and the processes of Bergmann glia in the molecular layer. The MeCP2 antibody specifically labels nuclei of certain neurons. |
 |
| Chromogenic immunostaining of a formalin fixed paraffin embedded human cerebellum section with rabbit pAb to GFAP, 2539, dilution 1:5,000, detected with DAB (brown) using the Vector Labs ImmPRESS method and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. The 2539 antibody labels the processes of astrocytes within both the granular and molecular layers and Bergmann glia in the molecular layer. This antibody performs well in testing with both 4% PFA and standard NBF fixed rat, mouse, and human tissues. |
 |
| Immunofluorescent analysis of cortical neuron-glial cell culture from E20 rat stained with rabbit polyclonal antibody to GFAP, 2539, dilution 1:5,000 in red, and chicken polyclonal antibody to vimentin, 5866, dilution 1:10,000 in green. The blue is DAPI staining of nuclear DNA. The astrocytes containing GFAP only are red, GFAP and Vimentin are golden-yellow. Fibroblastic cells contain only vimentin, so they are green. |

| Above is an image generated in the Lifecanvas Technologies laboratory using 2539 and an appropriate secondary antibody on a 1mm section of rat brain. This was processed using the Lifecanvas SHIELD fixation protocol which employs a novel epoxy crosslinker (Park et al. Nature Biotechnology 2018). |
 |
| Western blot analysis of different tissue lysates using rabbit polyclonal antibody to GFAP, 2539, dilution 1:5,000 in green: [1] protein standard (red), [2] rat brain, [3] rat spinal cord, [4] mouse brain, [5] mouse spinal cord. Strong band at about 50kDa corresponds to the major isotype of the GFAP protein. Smaller isotypes and proteolytic fragments of GFAP are also detected on the blot. |
