Scientific Data Images for Mouse VEGFR1/Flt-1 Antibody

Cell Proliferation Induced by VEGF164and Neutralization by Mouse VEGFR1/Flt‑1 Antibody.

Cell Proliferation Induced by VEGF164and Neutralization by Mouse VEGFR1/Flt‑1 Antibody.

Recombinant Mouse VEGF164 493-MV) stimulates proliferation in HUVEC human umbilical vein endothelial cells in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse VEGF164(5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse VEGFR1/Flt-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF471). The ND50 is typically 2-8 µg/mL.

Background: VEGFR1/Flt-1

VEGFR1 is one of the five receptor tyrosine kinases (RTKs) (VEGFR1, KDR/Flk-1, Flt-4, Tie-1, and Tek/Tie-2) whose expression is almost exclusively restricted to the endothelial cells. Tie-1 and tek/tie-2 define a new class of RTKs containing two immunoglobulin-like domains, three EGF homology domains and three fibronectin type III domains in their extracellular regions. VEGFR1/Flt-1, VEGFR2/KDR/Flk-1, VEGFR3/Flt-4 are members of the class III subfamily of RTKs containing seven immunoglobulin-like repeats in their extracellular domains. All five RTKs are likely to play central roles in vasculogenesis and angiogenesis.

Full length mouse VEGFR1 mRNA encodes a 1333 amino acid (aa) residue precursor with a predicted 22 aa residue signal peptide. Mature VEGFR1 is composed of a 737 aa residue extracellular domain, a 22 aa residue transmembrane domain and a 552 aa residue cytoplasmic domain. As a result of alternative splicing of the mRNA, a cDNA encoding a truncated form of VEGFR1, lacking the seventh immunoglobulin-like domain, the transmembrane and intracellular domains, has been cloned. The recombinant soluble VEGFR1/Fc chimera binds VEGF and PlGF with high affinity and is a potent VEGF antagonist.
