Scientific Data Images for Human VEGFR2/KDR/Flk-1 Antibody

Detection of VEGFR2/KDR/Flk‑1 in HUVEC Human Cells by Flow Cytometry.

HUVEC human umbilical vein endothelial cells were stained with Mouse Anti-Human VEGFR2/KDR/Flk-1 Monoclonal Antibody (Catalog # MAB3572R, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B).

VEGFR2/KDR Inhibition of VEGF-dependent Cell Proliferation and Neutralization by Human VEGFR2/KDR Antibody.

Recombinant Human VEGFR2/KDR Fc Chimera (Catalog # 357-KD) inhibits Recombinant Human VEGF₁₆₅(Catalog # 293-VE) induced proliferation in HUVEC human umbilical vein endothelial cells in a dose-dependent manner (orange line). Inhibition of Recombinant Human VEGF₁₆₅(10 ng/mL) activity elicited by Recombinant Human VEGFR2/KDR Fc Chimera (50 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human VEGFR2/KDR Monoclonal Antibody (Catalog # MAB3572R). The ND₅₀ is typically 10-50 ng/mL.

Applications for Human VEGFR2/KDR/Flk-1 Antibody

Application

Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Flow Cytometry

0.25 µg/10⁶ cells
Sample: HUVEC Human Cells

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 10-50 ng/mL in the presence of 50 ng/mL Recombinant Human VEGFR2/KDR/Flk‑1 Fc Chimera and 10 ng/mL Recombinant Human VEGF₁₆₅.

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. Mature VEGFR2 is composed of a 745 aa extracellular domain, a 25 aa transmembrane domain and a 567 aa cytoplasmic domain. In contrast to VEGFR1 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.
