Protein Description	Recombinant Human Soluble VEGFR-1 (D1-4). Recombinant Human soluble Vascular Endothelial Growth Factor Receptor-1 domain D1-4 (sVEGFR-1D1-4) is produced as a non-chimeric protein in a monomeric form. The soluble receptor protein contains only the first 4 extracellular domains, which contain all the information necessary for binding of VEGF. The receptor monomers have a mass of approximately 55kDa containing 457 amino acid residues. Result by N-terminal sequencing: SGSKLKD
Note	Centrifuge vials before opening!
Storage	Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing.
Stability	Shelf life: one year from despatch.
Bioactivity	Biological: The activity of sVEGFR-1D1-4 was determined by its ability to inhibit the VEGF-A-induced proliferation of HUVECs.
Endotoxin	< 0.1 ng per µg of VEGFR-1.

Summary	This gene encodes a member of the vascular endothelial growth factor receptor (VEGFR) family. VEGFR family members are receptor tyrosine kinases (RTKs) which contain an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and a tyrosine kinase (TK) domain within the cytoplasmic domain. This protein binds to VEGFR-A, VEGFR-B and placental growth factor and plays an important role in angiogenesis and vasculogenesis. Expression of this receptor is found in vascular endothelial cells, placental trophoblast cells and peripheral blood monocytes. Multiple transcript variants encoding different isoforms have been found for this gene. Isoforms include a full-length transmembrane receptor isoform and shortened, soluble isoforms. The soluble isoforms are associated with the onset of pre-eclampsia.[provided by RefSeq, May 2009]
