Recombinant Human KDR

Cat. No.: KDR-61H
Product Overview: Recombinant Human KDR contains only the first 7 extracellular domains, which contain all the information necessary for ligand binding. The protein is purified by proprietary chromatographic techniques.
Description: Vascular endothelial growth factor (VEGF) is a major growth factor for endothelial cells. This gene encodes one of the two receptors of the VEGF. This receptor, known as kinase insert domain receptor, is a type III receptor tyrosine kinase. It functions as the main mediator of VEGF-induced endothelial proliferation, survival, migration, tubular morphogenesis and sprouting. The signalling and trafficking of this receptor are regulated by multiple factors, including Rab GTPase, P2Y purine nucleotide receptor, integrin alphaVbeta3, T-cell protein tyrosine phosphatase, etc.. Mutations of this gene are implicated in infantile capillary hemangiomas.
Source: Insect Cells
Molecular Mass: Recombinant Human KDR produced in baculovirus is monomeric, glycosylated, polypeptide having a molecular mass of 116 kDa.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: KDR was lyophilized from a concentrated (1 mg/ml) sterile solution containing 25mM MES pH-5.5 and 100mM NaCl.
Purity: Greater than 95.0% as determined by SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized VEGFR2 in sterile water not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: The activity of VEGFR2 D1-7 was determined by its ability to abolish the binding of iodinated VEGF to solid surfaces or cell surfaces receptors. The ED50 for this effect is typically 10.0 ng/ml, corresponding to a specific activity of 100,000IU/mg.

Stability: Lyophilized VEGFR-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FLK1 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.
