C57BL/6 mouse frozen brain tissue was fixed with 4% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5 % Triton X-100 for ten minutes, and blocked with 5% FBS for 30 minutes. Then the tissue was stained with 1.25 µg/ml of Brilliant Violet 421™ anti-GFAP (clone 2E1.E9, blue) overnight at 4°C. Nuclei were counterstained with DRAQ5™ (red). The image was captured with a 10X objective.

    Day-three cultured postnatal C57BL/6 mouse brain cells were fixed with 1% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5% Triton X-100 for ten minutes, and blocked with 5% FBS for 30 minutes. Then, the cells were intracellularly stained with 5 µg/ml of anti-GFAP (clone 2E1.E9) Brilliant Violet 421™ in 5% FBS overnight at 4°C. Nuclei were counterstained with DRAQ5™ (blue). The image was captured with a 40X objective.

    Human paraffin-embedded human cerebellum tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Tris-Buffered Saline 1X (1.0M, pH 7.4) at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with Brilliant Violet 421™ anti-GFAP Antibody (clone 2E1.E9, blue) at 4°C overnight. The nuclei were counter stained with DRAQ5™ (red). The image was captured with a 10X objective.

Description

GFAP is expressed exclusively in astrocytes in the central nervous system. The protein is a member of the intermediate filament family of proteins which form networks providing support and strength to cells. This antibody does not cross-react with other intermediate filaments such as vimentin, neurofilament proteins, desmin and others. More than 50 GFAP mutations have been identified to be associated with the Alexander disease.

Recommended Usage

Each lot of this antibody is quality control tested by immunohistochemical staining on frozen tissue sections. For immunohistochemistry, a concentration range of 1.25 - 5.0 µg/mL is suggested. For immunocytochemistry, a concentration range of 2.5 - 5.0 μg/mL is recommended. For immunohistochemical staining on formalin-fixed paraffin-embedded tissue sections, the suggested use of this reagent is 5.0 - 10 µg per mL. It is recommended that the reagent be titrated for optimal performance for each application.

Brilliant Violet 421™ excites at 405 nm and emits at 421 nm. The standard bandpass filter 450/50 nm is recommended for detection. Brilliant Violet 421™ is a trademark of Sirigen Group Ltd.

Antigen Details

Structure
Around 50 kD
Distribution

Only expressed in astrocytes in the central nervous system.

Function
Together with other proteins to form intermediate filaments which supports astroglial cells. Astroglial cells support and nourish cells in the brain and spinal cord. If brain cells are injured through trauma or disease, astroglial cells react by rapidly prodcing more GFAP protein.
