Vascular endothelial growth factor receptor-2 (VEGFR-2), also known as KDR (human) and Flk1 (mouse), is an endothelial cell receptor tyrosine kinase with seven extracellular Ig-like domains. These domains contain a ligand binding site, a single transmembrane domain, and an intracellular region containing the tyrosine kinase domain split by a non-catalytic kinase insert domain. Upon binding its ligand, VEGF, VEGFR-2 undergoes dimerization that in turn activates its tyrosine kinase activity, resulting in the auto-phosphorylation of several tyrosines (Tyr951/996 and Tyr1054/1059). Ligand-independent activation of VEGFR-2 and the subsequent activation of PI-3K/ Akt and eNOS has been observed with fluid shear stress in blood vessels, thereby leading to the production of NO and regulation of vascular homeostasis. VEGFR-2 is a critical mediator of the angiogenic functions of VEGF, and is an attractive target for anti-angiogenic drugs relating to disease states such as cancer, macular degeneration, and diabetic retinopathy.


VEGFR-2/KDR Singleplex Products

Our VEGFR-2/KDR immunoassays provide fast, accurate, reproducible, and highly sensitive measurements of VEGFR-2/KDR. MSD’s MULTI-ARRAY technology uses simple protocols, requires minimal sample, and quantifies analyte concentration over a wide dynamic range.
