Applications

Recommended Concentration

Sample

Mouse VEGFR2/Flk-1 Sandwich Immunoassay

Recommended Concentration

Reagent

ELISA Capture (Matched Antibody Pair)

2-8 µg/mL

Use in combination with:

Detection Reagent: Mouse VEGFR2/KDR/Flk-1 Biotinylated Antibody (Catalog # BAF644)

Standard: Recombinant Mouse VEGFR2/Flk-1 Fc Chimera Protein (Catalog # 443-KD)

Neutralization

Measured by its ability to neutralize VEGFR2/KDR/Flk‑1-mediated inhibition of proliferation in HUVEC human umbilical vein endothelial cells. The Neutralization Dose (ND₅₀) is typically 0.05-0.15 µg/mL in the presence of 150 ng/mL Recombinant Mouse VEGFR2/KDR/Flk‑1 Fc Chimera and 5 ng/mL Recombinant Mouse VEGF₁₆₄.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

VEGFR2/KDR/Flk‑1 Inhibition of VEGF-dependent Cell Proliferation and Neutralization by Mouse VEGFR2/KDR/Flk‑1 Antibody. Recombinant Mouse VEGFR2/KDR/Flk-1 Fc Chimera (Catalog # 443-KD) inhibits Recombinant Mouse VEGF₁₆₄(Catalog # 493-MV) induced proliferation in HUVEC human umbilical vein endothelial cells in a dose-dependent manner (orange line). Inhibition of Recombinant Mouse VEGF₁₆₄(5 ng/mL) activity elicited by Recombinant Mouse VEGFR2/KDR/Flk-1 Fc Chimera (150 ng/mL) is neutralized (green line) by increasing concentrations of Mouse VEGFR2/KDR/Flk-1 Monoclonal Antibody (Catalog # MAB4431). The ND₅₀ is typically 0.05-0.15 µg/mL.

Background: VEGFR2/KDR/Flk-1

VEGFR2 (KDR/Flk-1), VEGFR1 (Flt-1) and VEGFR3 (Flt-4) belong to the class III subfamily of receptor tyrosine kinases (RTKs). All three receptors contain seven immunoglobulin-like repeats in their extracellular domains and kinase insert domains in their intracellular regions. The expression of VEGFR1, 2, and 3 is almost exclusively restricted to the endothelial cells. These receptors are likely to play essential roles in vasculogenesis and angiogenesis. Mouse VEGFR2 cDNA encodes a 1367 amino acid (aa) precursor protein with a 19 aa signal peptide. Mature VEGFR2 is composed of a 743 aa extracellular domain, a 22 aa transmembrane domain, and a 583 aa cytoplasmic domain. In contrast to VEGF R1 which binds both PlGF and VEGF with high affinity, VEGFR2 binds VEGF but not PlGF with high affinity. The recombinant soluble VEGFR2/Fc chimera binds VEGF with high affinity and is a potent VEGF antagonist.
