GFAP is an astrocyte-specific type-III intermediate filament protein
Mouse monoclonal purified IgG
Cat. No.: 173 011AT488
Amount: 100 µg
Price: $465.00
Cat. No. 173 011AT488 100 µg purified IgG, lyophilized, fluorescence-labeled with ATTO® 488.

For many of the fluorescence labeled antibodies conjugated to ATTO® dyes from ATTO-TEC the established fluorescence detection systems can be used.

ATTO® 488: λex 500 nm / λem 520 nm
ATTO® 550: λex 554 nm / λem 576 nm
ATTO® 565: λex 564 nm / λem 590 nm
ATTO® 594: λex 603 nm / λem 626 nm
ATTO® 647N: λex 646 nm / λem 664 nm
 

ATTO®488, ATTO®565, ATTO®647N and ATTO®594 dyes are suitable for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy.
ATTO®488, ATTO®565 and ATTO®594 are also recommended for PALM and dSTORM high resolution microscopy.

Albumin and azide were added for stabilization. For reconstitution add 100 µl H2O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives.
Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.

Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Background

Glial fibrillary acidic protein GFAP is a glial-specific member of the intermediate filament protein family. This group comprises cell type-specific filamentous proteins with similar structure and function as scaffold for cytoskeleton assembly and maintenance.
Frequently, neural stem cells also express GFAP. In addition many types of brain tumors, probably derived from astrocytic cells, heavily express GFAP. This protein is also found in the lens epithelium, Kupffer cells of the liver, in some cells in salivary tumors and others.
Point-mutations in the GFAP gene have been correlated to Alexander disease, a fatal leukoencephalopathy that leads to the dysmyelination or demyelination of the central nervous system.
