Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Specificity / Sensitivity
Phospho-VEGF Receptor-2 (Tyr1212) (11A3) Rabbit mAb detects transfected levels of VEGFR-2 only when phosphorylated at tyrosine 1212. The antibody does not cross-react with other phosphorylated receptor tyrosine kinases.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr1214 of human VEGF receptor-2.
Western blot analysis of recombinant human GST-VEGF Receptor 2 (Val789-Val1356), untreated or λ phosphatase-treated, using Phospho-VEGF Receptor 2 (Tyr1212) (11A3) Rabbit mAb (upper) and VEGF Receptor 2 Antibody #2472 (lower).
Phospho-VEGF Receptor 2 (Tyr1212) (11A3) Rabbit mAb specifically binds to phosphorylated VEGFR2, but not other phosphorylated tyrosine kinases. Western blot analysis of extracts from cells expressing different activated tyrosine kinase proteins, using Phospho-VEGF Receptor-2 (Tyr1212) (11A3) Rabbit mAb (upper) and Phospho-Tyrosine mAb (P-Tyr-100) #9411 (lower). CKR/PAE cells (lanes 12 and 13) express chimeric receptors containing human CSF-1 extracellular binding domain/mouse VEGF receptor-2 intracellular domain (5). CSF-1 stimulates phosphorylation of Tyr1212 of intracellular VEGF receptor-2 domain (lane 12) , which was specifically detected by Phospho-VEGF Receptor-2 (Tyr1212) (11A3) Rabbit mAb.
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 in vitro and angiogenesis in vivo (6-8).
