描述（Description）
The Human VEGF R2 (Luc) HEK293 Reporter Cell was engineered to not only express NFAT signaling response element, but also express the receptor full length human VEGF R2 (Gene ID: 3791). When stimulated with human VEGF protein, the VEGF/VEGF R2 interaction drives NFAT-mediated luminescence. Inhibition of VEGF binding to VEGF R2 by either anti-VEGF or anti-VEGF R2 antibodies results in a decrease in luminescence.

Receptor Assay
Expression analysis of human VEGF R2 on Human VEGF R2 (Luc) HEK293 Reporter Cell by FACS.
Cell surface staining was performed on Human VEGF R2 (Luc) HEK293 Reporter Cell or negative control cell using PE-labeled anti-VEGF R2 antibody.
Protocol
Application
Inhibition of human VEGF165 protein-induced reporter activity by anti-human VEGF neutralizing antibody.
This reporter cell was incubated with serial dilutions of antibodies in the presence of human VEGF165 protein (Cat. No. VE5-H4210) with a final concentration of 10 ng/mL. The EC50 of anti-human VEGF neutralizing antibody (Bavacizumab) is approximately 0.0071 μg/mL.
Protocol
Inhibition of human VEGF165 protein-induced reporter activity by human VEGF R2 small molecule inhibitor.
This reporter cell was incubated with serial dilutions of inhibitors in the presence of human VEGF165 protein (Cat. No. VE5-H4210) with a final concentration of 10 ng/mL. The EC50 of human VEGF R2 small molecule inhibitor (Cabozantinib) was approximately 0.0053 μM.
Protocol
Signaling Bioassay
Response to human VEGF165 protein (RLU).
The Human VEGF R2 (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human VEGF165 protein (Cat. No. VE5-H4210). The EC50 was approximately 5.13 ng/mL.
Protocol
Response to human VEGF165 protein (Fold).
The Human VEGF R2 (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human VEGF165 protein (Cat. No. VE5-H4210). The max induction fold was approximately 70.
Protocol
Passage Stability
Passage stability analysis by Signaling Bioassay.
The continuously growing Human VEGF R2 (Luc) HEK293 Reporter Cell was stimulated with serial dilutions of human VEGF165 protein. Human VEGF165 protein stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 10-32.

背景（Background）
Vascular endothelial growth factor (VEGF) is a potent angiogenic inducer that stimulates the expression of tissue factor (TF), the major cellular initiator of blood coagulation. VEGF could inhibit apoptosis and increase cellular proliferation. As the most abundant splice variant of VEGF-A, VEGF165 binds to the receptor tyrosine kinases, VEGFR1 and VEGFR2, leads to activation of the PI3K/AKT, p38 MAPK, FAK, and paxillin. Due to the angiogenesis ability of VEGF in cancer, interfering VEGF/VEGFR2 interaction has become an attractive method in cancer therapy.
