GFAP (Glial fibrillary acidic protein) is a type III intermediate filament protein. It is the major component of astrocyte intermediate filament. Defects in GFAP are a cause of Alexander disease. 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. At the amino acid sequence level, human GFAP shares 91% and 90% identity with rat and mouse GFAP, respectively.

Scientific Data Images for Human/Rat GFAP Antibody
Detection of Human and Rat GFAP by Western Blot.
Western blot shows lysates of rat cortical stem cells, rat brain tissue, human brain (cortex) tissue, and human brain (hypothalamus) tissue. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human GFAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2594) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Specific bands were detected for GFAP at approximately 35-50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.beta ‑III Tubulin in Rat Cortical Neurons and GFAP in Rat Astrocytes.
beta -III Tubulin was detected in rat cortical neurons using 5 µg/mL Mouse Anti-neuron-specific Mouse beta -III Tubulin Monoclonal (clone TuJ-1) Antibody (Catalog # MAB1195). GFAP was detected in rat astrocytes using 10 µg/mL Sheep Anti-Human GFAP Antigen Affinity-purified Poly-clonal Antibody (Catalog # AF2594). Cells were incubated with primary antibodies for 3 hours at room temperature. Cells were stained for beta-III Tubulin using the Northern-Lights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and for GFAP using the Northern-Lights 493-conjugated Anti-Sheep IgG Secondary Antibody (green; Catalog # NL012).

GFAP was detected in immersion fixed rat astrocytes using 10 µg/mL Sheep Anti-Human GFAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2594) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue).

GFAP was detected in immersion fixed 7 days differentiated rat cortical stem cells using Sheep Anti-Human GFAP Antigen Affinity-purified Poly-clonal Antibody (Catalog # AF2594) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the Northern-Lights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (yellow; Catalog # NL010) and counterstained with DAPI (blue).

Simple Western lane view shows lysates of human brain (cerebellum) tissue, loaded at 0.2 mg/mL. A specific band was detected for GFAP at approximately 51 kDa (as indicated) using 0.1 µg/mL of Sheep Anti-Human/Rat GFAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2594) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Detection of Rat GFAP by Simple WesternTM.
Simple Western lane view shows lysates of rat brain tissue, loaded at 0.2 mg/mL. A specific band was detected for GFAP at approximately 55 kDa (as indicated) using 2 µg/mL of Sheep Anti-Human/Rat GFAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2594) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Detection of GFAP by Immunocytochemistry/ Immunofluorescence
