Description
General description
Annexin A1 (ANXA1) belongs to the annexin gene family and is a part of the A subfamily. It is a glucocorticoid-regulated, calcium and phospholipid-binding protein. This protein has a molecular weight of 37kDa.
Immunogen
Annexin A1 recombinant protein epitope signature tag (PrEST)
Application
Anti-ANXA1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem/physiol Actions
Annexin A1 (ANXA1) is involved in multiple cellular functions such as, cell proliferation and differentiation and signal transduction. Its expression is deregulated in various cancers such as, glial tumors, nasopharyngeal carcinoma, head and neck, larynx, esophageal, breast, hepatocellular, gastric, prostate and pancreatic cancer. It is up-regulated in rectal cancer and predicts poor prognostic response to concurrent chemoradiotherapy. ANXA1 is involved in anti-inflammatory processes, and regulates apoptosis and phagocytosis of apoptotic bodies. Its expression levels are altered in cystic fibrosis, and might be involved in the pathogenesis of glomerular disorders. It has potential as a marker for the diagnosis and prognosis of glomerular disorders. ANXA1 has a high level of expression in normal gastrointestinal epithelium, and might be involved in the maintenance of cellular boundaries. It also regulates gastric cancer cell proliferation and viability through COX2 (cyclooxygenase 2) pathway.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
Protein array of 364 human recombinant protein fragments.
Physical form
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
Other Notes
Corresponding Antigen APREST71575
