Our VEGFR-3 (N-terminus) rabbit polyclonal primary antibody from PhosphoSolutions is produced in-house. It detects human, rat VEGFR-3 (N-terminus) and is antigen affinity purified. It is great for use in WB.
Left: Western blot image of human K-562 cells (lanes 1 & 2) and HUVEC (lanes 3 & 4). The blots were probed with rabbit polyclonal anti-VEGFR-3 (a.a. 1285-1298) in the absence (lanes 1 & 3) or presence of blocking peptide (VX2945) (lanes 2 & 4). Right: Western blot image of GST-recombinant human VEGFR-1 (89 kDa), VEGFR-2 (110 kDa), and VEGFR-3 (86 kDa) C-terminal regions. The blot was probed with anti-VEGFR-3 (a.a. 1285-1298).
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.

WB: 1:1000
Unconjugated
The antibody detects a 170 kDa* band corresponding to VEGFR-3 in western blots of human endothelial and K-562 cells, and shows strong reactivity to recombinant human VEGFR-3, but not VEGFR-1 or VEGFR-2.
