Product Information
The rapid protocol PathScan® RP Phospho-VEGFR-2 (Tyr1175) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of Phospho-VEGFR-2 (Tyr1175) protein in a reduced assay time of 1.5 hours.
Incubation of cell lysates and detection antibody on the coated microwell plate forms a sandwich with VEGFR2 protein phosphorylated at Tyr1175 in a single step. The plate is then extensively washed and TMB reagent is added for signal development. The magnitude of absorbance for the developed color is proportional to the quantity of VEGFR2 protein phosphorylated at Tyr1175. Learn more about all of your ELISA kit options here.
*Antibodies in kit are custom formulations specific to kit.
NOTE: This protocol is for PathScan® kits that use an HRP directly conjugated to the detection antibody (Rapid Protocol), rather than a 2-step method where the detection antibody and a secondary-HRP are added sequentially.
NOTE: Prepare solutions with deionized/purified water or equivalent.
For adherent cells
For suspension cells
NOTE: Equilibrate all materials and prepared reagents to room temperature prior to running the assay.
NOTE: Initial color of positive reaction is blue, which changes to yellow upon addition of STOP Solution.

Protocol Id: 2144
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).
