Specifically recognizes mammalian GFAP on western blots and immunocytochemically. Detects a band of 55kDa corresponding to GFAP and also a GFAP derived 48kDa band. Some customers have successfully used ab7260 on Zebrafish lysates; however we have conflicting data to suggest that not all batches will be suitable for work on Zebrafish.

Anti-GFAP antibody (ab7260) specifically detects GFAP (UniProt ID: P14136; Molecular weight: 50kDa) and is sold in 50 µL selling sizes.

GFAP (Glial Fibrillary Acidic Protein) is a key marker in neuro research, particularly for its role in identifying astrocyte activity. It is predominantly expressed in astrocytes, the most abundant glial cells in the brain and spinal cord. Altered GFAP levels are associated with various neurological conditions, including Alzheimer's disease (AD), traumatic brain injury (TBI) and multiple sclerosis (MS). Researchers use GFAP to assess astrocytic response and neuroinflammation, making it essential for understanding the extent of brain injury and the progression of neurodegenerative diseases.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-GFAP antibody (ab7260)

    IHC image of GFAP staining in a formalin fixed, paraffin embedded normal mouse brain tissue section, performed on a Leica Bond™ system using the standard protocol B.

    The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab7260 at 1/2000 dilution for 15 mins at room temperature. A goat anti-rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with hematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-GFAP antibody (ab7260)

    Increases in GFAP after demyelinating injury are greater in the spinal cord compared to brain

    Photomicrographs show immunoreactivity for GFAP or ALDH1L1 in (A) the corpus callosum, or (B) the dorsal column white matter of adult mice at base line, and at 14 d after microinjection of the demyelinating agent lysolecithin. Histograms show the percent area of GFAP immunofluorescence, and expression of GFAP/ALDH1L1+ astrocyte, was significantly greater in the spinal cord compared to the corpus callosum 14d post-lysolecithin lesion.

    GFAP was detected using ab7260.
