GFAP antibody - 173 009 K.O.

GFAP is an astrocyte-specific type-III intermediate filament protein
Chicken monoclonal recombinant IgY
Cat. No.: 173 009
Amount: 50 µg
Price: $415.00
Cat. No. 173 009 50 µg purified recombinant IgY, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.
Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications
 
WB: 1 : 1000 (AP-staining) (see remarks) gallery  
IP: not tested yet
ICC: 1 : 500 gallery  
IHC: 1 : 500 gallery  
IHC-P: 1 : 200 gallery  

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.

Remarks

This antibody is a chimeric antibody based on the monoclonal mouse antibody 134B1. The constant regions of the heavy and light chains have been replaced by chicken specific sequences. The antibody can therefore be used with standard anti-chicken secondary reagents. The antibody has been expressed in mammalian cells.
WB: In Western blots, the monoclonal GFAP antibodies are less sensitive than the polyclonal rabbit and guinea pig GFAP antibodies.

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.
