Vascular Endothelial Growth Factor Receptor-1 D5 Human Recombinant

Product Name Vascular Endothelial Growth Factor Receptor-1 D5 Human Recombinant
Synonyms FLT-1, FLT1, Tyrosine-protein kinase receptor FLT, Flt-1, Tyrosine-protein kinase FRT, Fms-like tyrosine kinase 1, VEGFR-1.
Description Soluble FLT1 D1-5 Human Recombinant produced in baculovirus is monomeric, glycosylated, polypeptide containing 562 amino acids and having a molecular mass of 70 kDa. The soluble receptor protein contains only the first 5 extracellular domains, which contain all the information necessary for binding of VEGF.The FLT1 is purified by proprietary chromatographic techniques.

Amino Acid Sequence

Source Insect Cells.
Physical Appearance and Stability Lyophilized FLT-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FLT1 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity FLT1 D1-5 was lyophilized from a concentrated (1 mg/ml) sterile solution containing no additives. Greater than 90.0% as determined by(a)Analysis by RP-HPLC.(b)Analysis by SDS-PAGE.
Solubility It is recommended to reconstitute the lyophilized FLT1 D5 in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The activity of FLT1 D5 was determined by its ability to abolish the binding of iodinated VEGF to solid surfaces or cell surfaces. The ED50 for this effect is typically 10 ng/ml, corresponding to a specific activity of 100,000IU/mg. In a 13 day CAM-assay sVEGFR-1 is able to inhibit VEGF stimulated sprouting of capillaries at 30 pM.
Shipping Format and Condition Lyophilized powder at room temperature.
