CST, 2474T, Phospho-VEGF Receptor 2 (Tyr996) Antibody

Polyclonal Antibody for studying VEGFR2 (Tyr996) phosphate. Validated for Western Blotting. Available in 2 sizes. Highly specific and rigorously validated in-house, Phospho-VEGF Receptor 2 (Tyr996) Antibody (CST #2474) is ready to ship. Product Usage Information Western Blotting: 1:1000 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity Phospho-VEGF Receptor 2 (Tyr996) Antibody detects transfected VEGFR 2 only when phosphorylated at tyrosine 996. This antibody cross-reacts with tyrosine-phosphorylated PDGF receptor. Species Reactivity: Human, Mouse Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr996 of human VEGF receptor 2. Antibodies are purified by protein A and peptide affinity chromatography. Background Vascular endothelial growth factor receptor 2 (VEGFR2, KDR, Flk-1) is a major receptor for VEGF-induced signaling in endothelial cells. Upon ligand binding, VEGFR2 undergoes autophosphorylation and becomes activated (1). Major autophosphorylation sites of VEGFR2 are located in the kinase insert domain (Tyr951/996) and in the tyrosine kinase catalytic domain (Tyr1054/1059) (2). Activation of the receptor leads to rapid recruitment of adaptor proteins, including Shc, GRB2, PI3 kinase, NCK, and the protein tyrosine phosphatases SHP-1 and SHP-2 (3). Phosphorylation at Tyr1212 provides a docking site for GRB2 binding and phospho-Tyr1175 binds the p85 subunit of PI3 kinase and PLCγ, as well as Shb (1,4,5). Signaling from VEGFR2 is necessary for the execution of VEGF-stimulated proliferation, chemotaxis and sprouting, as well as survival of cultured endothelial cells and angiogenesis (6-8).
