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

VEGFR2/KDR/Flk-1 antibody in Mouse Embryo by Immunohistochemistry (IHC-Fr).

VEGFR2/KDR/Flk‑1 in Mouse Embryo.

VEGFR2/KDR/Flk-1 was detected in immersion fixed frozen sections of mouse embryo (14 d.p.c.) using 15 µg/mL Goat Anti-Mouse VEGFR2/KDR/Flk-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF644) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to mesenchymal cells.

VEGFR2 antibody in Mouse Kidney Tissue.

VEGFR2 in Mouse Kidney Tissue.

VEGFR2 was detected in acetone fixed cryosections of mouse kidney tissue using Goat Anti-Mouse VEGFR2/KDR/Flk-1 Polyclonal Antibody (Catalog # AF644) for 50 minutes at room temperature. Tissues were stained with rabbit anti-goat secondary antibody and HRP polymer-conjugated anti-rabbit IgG followed by AEC+Substrate Chromogen (red) followed by counterstaining with hematoxylin (blue). Experiments were carried out and the image was provided by Dr. Grietje Molema, University Medical Center Groningen, The Netherlands.
VEGFR2/KDR/Flk‑1 Inhibition of VEGF-dependent Cell Proliferation and Neutralization by Mouse VEGFR2/KDR/Flk‑1 Antibody.

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 (50 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse VEGFR2/KDR/Flk-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF644). The ND50 is typically 0.1-0.3 µg/mL.

Applications for Mouse 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

2.5 µg/106 cells
Sample: bEnd.3 mouse endothelioma cell line

Immunohistochemistry

5-15 µg/mL
Sample: Immersion fixed frozen sections of mouse embryo (14 d.p.c.) and acetone fixed cryosections of mouse normal kidney tissue

Western Blot

0.1 µg/mL
Sample: Recombinant Mouse VEGFR2/KDR/Flk‑1 Fc Chimera (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 0.1-0.3 µg/mL in the presence of 50 ng/mL Recombinant Mouse VEGFR2/KDR/Flk‑1 Fc Chimera and 5 ng/mL Recombinant Mouse VEGF164.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

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) residue precursor protein with a 19 aa residue signal peptide. Mature VEGFR2 is composed of a 743 aa residue extracellular domain, a 22 aa residue transmembrane domain and a 583 aa residue 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.
