Product Data
Description VEGFR-1 / Flt-1 (Fc Chimera) human recombinant protein, 10 µg
Species Human
Expression Host Insect
Predicted MW 130 kDa
Purity >90% by SDS-PAGE and visualised by silver stain.
Buffer Presentation State: Purified
State: Lyophilized purified protein.
Buffer System: PBS, pH 7.4 without stabilizers.
Bioactivity Biological: The activity of sVEGFR-1/Fc was determined by its ability to inhibit the VEGF-dependent proliferation of human umbilical vein endothelial cells.
The ED50 for this effect is typically 10-30 ng/ml.
Endotoxin < 0.1 ng per ug of sVEGFR-1
Reconstitution Restore in water or medium to a concentration not lower than 50 µg/ml.
The lyophilised sVEGFR-1/Fc is soluble in water and most aqueous buffers.
Preparation Lyophilized purified protein.
Protein Description Recombinant Human soluble Vascular Endothelial Growth Factor Receptor-1 (sVEGFR-1D1-7) was fused with the Fc part of human IgG1. The recombinant mature sVEGFR-1D1-7/Fc is a disulfide-linked homodimeric protein. The sVEGFR-1D1-7/Fc monomers have a mass of approximately 130 kDa. The soluble receptor protein consists of all 7 extracellular domains (Met1-Thr751), which contain all the information necessary for high affinity ligand binding.
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.

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]
