Western Blotting
Western blot analysis of extracts from HUVE cells, untreated or stimulated with VEGF (50 ng/ml for 2 minutes), using Phospho-VEGF Receptor 2 (Tyr1175) (19A10) Rabbit mAb.
Western Blotting
Phospho-VEGF Receptor 2 (Tyr1175) (19A10) 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 (Tyr1175) (19A10) 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 (7). CSF-1 stimulates phosphorylation of Tyr1175 of intracellular VEGF receptor-2 domain (lane 12), which was specifically detected by Phospho-VEGF Receptor-2 (Tyr1175) (19A10) Rabbit mAb.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded HUVE cells, untreated (left) or VEGF treated (right).
IF-IC
Confocal immunofluorescent images of HUVE cells untreated (left) or stimulated with Vascular Endothelial Growth Factor (VEGF) #9943 (right) and labeled with Phospho-VEGF Receptor 2 (Tyr1175) (19A10) Rabbit mAb (top, green) and VEGF Receptor 2 (55B11) Rabbit mAb #2479 (bottom, green). Blue pseudocolor = DRAQ5 ® #4084 (fluorescent DNA dye).

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, 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 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).
