Human VEGF R2/KDR Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human VEGF R2/KDR Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ala20-Glu764.[Accession | P35968-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 86.2 kDa. Due to glycosylation, the protein migrates to 115-140 kDa based on Tris-Bis PAGE result.

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

纯度(Purity)

> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Human VEGF R2 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human VEGF R2 is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human VEGF R2 at 0.5μg/ml (100μl/Well). Dose response curve for Anti-VEGFR2 Antibody, hFc Tag with the EC50 of 4.5ng/ml determined by ELISA.

背景(Background)

Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFB and PGF, and plays an essential role in the development of embryonic vasculature, the regulation of angiogenesis, cell survival, cell migration, macrophage function, chemotaxis, and cancer cell invasion. The tyrosine kinase receptor vascular endothelial growth factor receptor 2 (VEGFR2) is a key regulator of angiogenesis.

分子别名(Synonyms)

CD309; KDR; VEGFR; VEGFR2; VEGFR-21; FLK1; KRD1; Ly73

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lypholized powder.
