GST-fusion protein containing the C-terminal 150aa residues of human VEGF receptor 2.
Vascular endothelial growth factor receptor 2 (VEGFR-2, KDR, Flk-1) is a major receptor transducing VEGF-induced signaling in endothelial cells. Upon ligand binding, VEGFR-2 undergoes autophosphorylation and becomes activated (1). Major autophosphorylation sites of VEGFR-2 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, PI-3 kinase, Nck and the protein tyrosine phosphatases SHP-1 and SHP-2 (3). The phosphorylation of Tyr1212 provides a docking site for GRB2 binding, and phospho-Tyr1175 binds with the p85 subunit of PI-3 kinase and PLCg, as well as Shb (5, 6). The signaling of VEGFR-2 is necessary for the execution of VEGF-stimulated proliferation, chemotaxis and sprouting, as well as survival of cultured endothelial cells in vitro and angiogenesis in vivo (4). Applications: Suitable for use in Western Blot, Immunoprecipitation, Immonofluorescence, Flow Cytometry, Immunohistochemistry, ELISA and Immunocytochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1:1000 Incubate membrane with diluted antibody in 5% BSA, 1X TBS, 0.1% Tween-20 at 4C with gentle shaking, overnight. Immunohistochemistry (Paraffin): 1:300 Immunoprecipitation: 1:100 Immunofluorescence (IF-IC): 1:100 Immunofluorescence (IF-F): 1:100 Flow Cytometry: 1:200 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
