2E1-E9_A488_GFAP_Antibody_1_021820
C57BL/6 mouse frozen brain section was fixed with 4% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5% Triton X-100 for ten minutes then blocked with 5% FBS plus 5% rat/mouse serum for 30 minutes at room temperature. Then the section was stained with 5 µg/ml of Alexa Fluor® 488 anti-GFAP (clone 2E1.E9) antibody (green) overnight at 4°C. The nuclei were counterstained with DAPI (blue). The image was captured with a 20X 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 2.5 µg/ml of anti-GFAP (clone 2E1.E9) Alexa Fluor® 488 in a blocking buffer overnight at 4°C. Nuclei were counterstained with DAPI (blue). The image was captured with a 40X 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 1.0 - 10 µg/mL is suggested. For immunocytochemistry, a concentration range of 0.1 -10 µg/mL is recommended. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1.0 - 10 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

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.
