{"product_id":"biolegend-648838","title":"Biolegend, 648838, Purified anti-Annexin A2, 25μg","description":"\u003cp\u003eAnnexin A2 (ANXA2), a member of the annexin family of calcium-dependent phospholipid-binding proteins. Annexin A2 contains a conserved core domain with four annexin repeats that facilitate calcium-dependent binding to negatively charged phospholipids. This protein plays roles in diverse cellular processes, including membrane trafficking, cytoskeletal rearrangement, fibrinolysis, inflammation, and cellular signal transduction. Annexin A2 contributes to the regulation of membrane dynamics and endocytosis by binding to negatively charged phospholipids in a calcium-dependent manner, facilitating vesicle aggregation, fusion, and cytoskeletal anchoring. It also supports actin filament organization, thereby influencing cellular shape, motility, and adhesion. Annexin A2 is involved in exocytosis and plays an essential role in the trafficking of proteins to and from the cell membrane. ANXA2 typically exists as a monomer or as a heterotetrameric complex with S100A10 (also known as p11), forming the Annexin A2\/S100A10 heterotetramer (A2t). This complex is crucial for extracellular and membrane-associated functions. The A2t complex acts as a co-receptor for tissue plasminogen activator (tPA) and plasminogen on endothelial cell surfaces, promoting the localized generation of plasmin, a key enzyme involved in clot breakdown and extracellular matrix remodeling.  Dysregulation of Annexin A2 expression or localization has been associated with various diseases. In cancer, Annexin A2 is frequently overexpressed and promotes tumorigenesis by enhancing cell proliferation, invasion, angiogenesis, and metastasis. It has been identified as a marker of poor prognosis in cancers such as breast, pancreatic, and lung cancer. Annexin A2 facilitates cancer cell migration through actin remodeling and matrix degradation, and its cell surface expression supports plasmin-mediated extracellular matrix breakdown, aiding invasion. \u003cbr\u003e\n25μg\u003cbr\u003e\nVerified Reactivity: Human, Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\u003cbr\u003e\nImmunogen: Recombinant full length human Annexin A2\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: WB - Quality tested IHC-P, ICC, ICFC - Verified\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by western blotting.
