PreparationProduced from sera of rabbits immunised with highly pure recombinant human soluble extracellular domain of Flt-1/VEGFR-1 (110 kDa) as the immunizing antigen. Anti-human VEGFR-1/Flt-1 was purified by antigen-affinity chromatography with immobilised recombinant soluble VEGFR-1/VEGFR-1 or by protein A chromatography.
AntigenRecombinant human soluble Flt-1(D1-5)
Synonymsvascular endothelial growth factor receptor-1; FLT1; VEGF receptor 1;
DescriptionEndothelial cells express three different vascular endothelial growth factor (VEGF) receptors, belonging to the family of receptor tyrosine kinases (RTKs). They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), VEGFR-3 (Flt-4). Their expression is almost exclusively restricted to endothelial cells, but VEGFR-1 can also be found on monocytes, dendritic cells and on trophoblast cells. The flt-1 gene was first described in 1990. The receptor contains seven immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular splited tyrosine kinase domain. Compared to VEGFR-2 the Flt-1 receptor has a higher affinity for VEGF but a weaker signaling activity. VEGFR-1 thus leads not to proliferation of endothelial cells, but mediates signals for differentiation. Interestingly a naturally occuring soluble variant of VEGFR-1 (sVEGFR-1) was found in HUVEC supernatants in 1996, which is generated by alternative splicing of the flt-1 mRNA.
