Vascular Endothelial Growth Factor Receptor 2, phosphorylated (Tyr951) (VEGF R2, Flk1, KDR, Receptor Tyrosine Kinase)
Description:
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. Major autophosphorylation sites of VEGFR-2 are located in the kinase insert domain (Tyr951/996) and in the tyrosine kinase catalytic domain (Tyr1054/1059). 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. 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. Signaling from 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.

Applications:
Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Western Blot: 1:1000
Immunohistochemistry (Paraffin): 1:125 Use citrate as the unmasking buffer and TBST-5%NGS as antibody diluent.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
