Species ReactivityHuman
BufferPBS
ReconstitutionThe lyophilized sVEGFR-3/FLT-4 is soluble in water and most aqueous buffers and should be reconstituted in PBS or medium to a concentration not lower than100 µg/ml.
Stability and StorageLyophilized samples are stable for greater than six months at -20 °C to -70 °C. Reconstituted sVEGFR-3/FLT-4 should be stored in working aliquots at -20 °C. Avoid repeated freeze-thaw cycles!
Synonymssoluble vascular endothelial growth factor receptor-3; FLT4; PCL; LMPH1A; fms-related tyrosine kinase 4
DescriptionRecombinant human soluble Vascular Endothelial Growth Factor Receptor-3 (sVEGFR-3/FLT-4) was fused with a carboxy-terminal 6X histidine-tag. The recombinant mature sVEGFR-3/FLT-4 is a glycosylated monomeric protein. The sVEGFR-3/FLT-4 monomers have a mass of approximately 120 kDa. The soluble receptor protein consists of all 7 extracellular domains (Met1-Glu774). All three VEGF receptors belong to the class III subfamily of receptor tyrosine kinases (RTKs) characterised by the seven immunoglobulin-like loops in the extracellular domain. The expression of VEGFR-1 to -3 is almost exclusively restricted to hematopoietic precursor cells, vascular and lymphatic endothelial cells and to the monocyte/macrophage lineage. They play key roles in vasculogenesis, hematopoiesis, angiogenesis and lymphangiogenesis. The FLT-4 cDNA encodes a 1298 amino acid (aa) residue precursor protein with a 23aa residue signal peptide. Mature VEGFR-3/FLT-4 is composed of a 751aa residue extracellular domain, a 22aa transmembrane domain and a 482aa residue cytoplasmic domain. Both VEGF family members VEGF-C and VEGF-D have been shown to bind and activate VEGFR-3/FLT-4. The Flt-4 gene is widely expressed in the early embryo but becomes restricted to the lymphatic endothelial a latter stages of development. It is important for lymphangiogenesis.
