FLT1 Mouse

FLT-1, FLT1, Tyrosine-protein kinase receptor FLT, Flt-1, Tyrosine-protein kinase FRT, Fms-like tyrosine kinase 1, VEGFR-1.

FLT1 Mouse Recombinant produced in HEK cells is a single, glycosylated, polypeptide chain (23-759 a.a) containing a total of 970 amino acids, having a molecular mass of 108.9kDa.
FLT1 is fused to a 233 amino acid hIgG-his tag at C-terminus and is purified by proprietary chromatographic techniques.

HEK 293.

Sterile Filtered colorless solution.

FLT1 protein solution (1mg/ml) containing 10% glycerol and PBS.

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Avoid multiple freeze-thaw cycles.

Greater than 85.0% as determined by SDS-PAGE. 

The ED50 range ≤ 50ng/ml and is measured by its ability to inhibit proliferation using HUVEC human umbilical vein endothelial cells in the presence of Human VEGF165.

Endothelial cells express 3 different vascular endothelial growth factor receptors: VEGFR-1 (Flt1), VEGFR-2 (KDR/Flk1), VEGFR-3 (Flt4) which are a part of the receptor tyrosine kinases family. Those receptors express mostly in endothelial cells, but VEGFR-1 can also be found on monocytes, dendritic cells and on trophoblast cells. Flt1 contains 7 immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular split tyrosine kinase domain. Flt-1, when compared to VEGFR-2 receptor has a higher affinity for VEGF but a weaker signalling activity. VEGFR-1 also mediates signals for differentiation.
