VEGFR2/KDR Protein, Human, Rec

蛋白长度：A DNA sequence encoding the extracellular domain of human VEGFR2 (NP_002244.1) (Met 1-Glu 764) was fused with the Fc region of human IgG1 at the C-terminus.

性质：

表达系统：HEK293 Cells

种属：Human

氨基酸序：Met1-Glu764

标签类型：C-hFc

分子量：The recombinant human VEGFR2/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 979 amino acids and predicts a molecular mass of 109 kDa. The apparent molecular mass of human VEGFR2/Fc monomer is approximatly 150-160 KDa in SDS-PAGE under reducing conditions due to glycosylation.

活性：1. Immobilized Human VEGF121 (Cat:10008-HNAH) at 2 μg/mL (100 μL/well) can bind Human VEGFR2/KDR (ECD, hFc Tag)(Cat:PH50475M4), the ECof Human VEGFR2/KDR (ECD, hFc Tag)(Cat:PH50475M4) is 6-48 ng/mL. 2. Measured by its ability to inhibit the VEGF-dependent proliferation of human umbilical vein endothelial cells (HUVEC). The EDfor this effect is typically 20-120 ng/mL in the presence of 10 ng/mL recombinant human VEGF165.

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method.

基因名称：kinase insert domain receptor

通用名：KDR

蛋白序参考：NP_002244.1

总结：VEGFR2 also called KDR or Flk-1, is identified as the receptor for VEGF and VEGFC and an early marker for endothelial cell progenitors, whose expression is restricted to endothelial cells in vivo. VEGFR2 was shown to be the primary signal transducer for angiogenesis and the development of pathological conditions such as cancer and diabetic retinopathy. It has been shown that VEGFR2 is expressed mainly in the endothelial cells, and the expression is upregulated in the tumor vasculature. Thus the inhibition of VEGFR2 activity and its downstream signaling are important targets for the treatment of diseases involving angiogenesis. VEGFR2 transduces the major signals for angiogenesis via its strong tyrosine kinase activity. However, unlike other representative tyrosine kinase receptors, VEGFR2 does not use the Ras pathway as major downstream signaling but rather uses the phospholipase C-protein kinase C pathway to signal mitogen-activated protein (MAP)-kinase activation and DNA synthesis. VEGFR2 is a direct and major signal transducer for pathological angiogenesis, including cancer and diabetic retinopathy, in cooperation with many other signaling partners; thus, VEGFR2 and its downstream signaling appear to be critical targets for the suppression of these diseases. VEGF and VEGFR2-mediated survival signaling are critical to endothelial cell survival, maintenance of the vasculature and alveolar structure, and regeneration of lung tissue. Reduced VEGF and VEGFR2 expression in emphysematous lungs has been linked to increased endothelial cell death and vascular regression.

形式：Lyophilized

纯度：> 90 % as determined by SDS-PAGE.

储存条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.

储存溶液：Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
