Anti-VEGFR-2 Antibody

Vascular endothelial growth factor receptor-2 (VEGFR-2/Flk-1/KDR) is the primary receptor for VEGF in endothelial cells. Other VEGFR family members, VEGFR-1 (Flt-1) and VEGFR-3 (Flt-4), can also transduce the intracellular signals of VEGF. However, the role of VEGFR-1 is observed mainly during embryonic angiogenesis and VEGFR-3 signaling may be restricted to specific types of endothelial cells. Major autophosphorylation sites of VEGFR-2 are located in the kinase insert domain (Tyr-951/996) and in the tyrosine kinase catalytic domain (Tyr-1054/1059) . Other sites, Tyr-1175 and Tyr-1212 provide docking sites for downstream signaling molecules. Activation of VEGFR-2 also phosphorylates Tyr-801, leading to PI3-kinase-Akt activation and increases in endothelial nitric oxide synthase activity. Phosphorylation of mutliple sites in VEGFR-2 is required for downstream activation of several signaling pathways that control proliferation, chemotaxis, and sprouting during angiogenesis.

Our VEGFR-2 rabbit polyclonal primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat VEGFR-2 and is antigen affinity purified. It is great for use in WB, ICC.

A synthetic peptide (coupled to carrier protein) corresponding to amino acids from the N-terminal region of human VEGFR-2. This sequence has high homology to rat and mouse VEGFR-2, and no significant homology to other VEGFR family members.

For research use only. Not intended for therapeutic or diagnostic use. Use of all products is subject to our terms and conditions, which can be viewed on our website.

The antibody detects a 180 kDa* band corresponding to VEGFR-2 in western blots of human endothelial cells, and shows strong reactivity toward recombinant human VEGFR-2, but not VEGFR-1 or VEGFR-3. The antibody also works for immunofluorescent staining of VEGFR-2 in HUVEC cells.
