    Product Information

    Product Description

    PathScan® Total VEGFR-2 Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of total VEGFR-2 protein. A VEGFR-2 mouse mAb has been coated onto the microwells. After incubation with cell lysates, Both nonphospho- and phospho-VEGFR-2 proteins are captured by the coated antibody. Following extensive washing, a VEGFR-2 rabbit mAb is added to detect the captured VEGFR-2 protein. HRP-linked anti-rabbit antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of optical density for this developed color is proportional to the quantity of total VEGFR-2 protein.

    *Antibodies in this kit are custom formulations specific to kit.

    Protocol

    Specificity / Sensitivity

    CST's PathScan® Total VEGFR-2 Sandwich ELISA Kit detects endogenous levels of total VEGFR-2 protein. Using PathScan® Phospho-VEGFR-2 (Tyr1175) Sandwich ELISA Kit #7335, a significant induction of phospho-VEGFR-2 in HUVEC cells treated with VEGF can be detected. However, the level of total VEGFR-2 (phospho and non-phospho), detected by this Sandwich ELISA Kit #7340, remains unchanged (Figure 1). This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

    Background

    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).
