Recombinant Human VEGFR-2 Protein (HEK293)，His

VEGFR-2

VEGFR-2 is a tyrosine-protein kinase of the cell surface receptors of VEGFA, VEGFC, and VEGFD that mediates activation of the MAPK1/ERK2, MAPK3/ERK1, and MAP kinase signaling pathways, as well as the AKT1 signaling pathway. VEGFR-2 can promote the proliferation, survival, migration and differentiation of endothelial cells. Overexpression of VEGFR-2 is associated with the development of tumors. VEGFR-2 Protein, Human (HEK293, His) is the recombinant human-derived VEGFR-2 protein, expressed by HEK293 , with C-His labeled tag.

1. Measured by its ability to inhibit the VEGF-dependent proliferation of HUVEC human umbilical vein endothelial cells. The ED50for this effect is 9-160 ng/mL in the presence of 10 ng/mL recombinant human VEGF165 (HY-P7110A). 2. Immobilized Human VEGFR2-His at 1μg/ml (100 μ l/well)can bind Anti-Human VEGFR2 mAb.The ED50 of Anti-Human VEGFR2 mAb is ≤36.55 ng/ml. Measured by its ability to inhibit the VEGF-dependent proliferation of HUVEC human umbilical vein endothelial cells. The ED50 for this effect is 9.805 ng/mL in the presence of 10 ng/mL recombinant human VEGF165, corresponding to a specific activity is 1.020×105 units/mg.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
