VEGF: Cutting off tumor's feeding channel

Immobilized Human VEGF R1&VEGF R2, Fc Tag at 2 μg/mL (100 μL/well) can bind Human VEGF165, His Tag (Cat. No. VE5-H5248) with a linear range of 0.004-0.063 μg/mL (QC tested).

Immobilized Human VEGF165, premium grade (MALS verified) (Cat. No. VE5-H4210) at 0.1 μg/mL (100 μL/well) can bind Human VEGF R1 Protein, His Tag (Cat. No. VE1-H52H9) with a linear range of 1.2-10 ng/mL (QC tested).

Immobilized Biotinylated Human VEGF165, His,Avitag (Cat. No. VE5-H82Q0) on CM5 Chip via Streptavidin, can bind Avastin with an affinity constant of 0.417 nM as determined in SPR assay (Biacore T200) (Routinely tested).
           
           

Loaded Avastin (Bevaciz*mab) on AHC Biosensor, can bind Human VEGF165, His Tag (Cat. No. VE5-H5248) with an affinity constant of 0.448 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
           
           

ActiveMax® Human VEGF165, Tag Free (MALS verified) (Cat. No. VE5-H4210) stimulates proliferation of human umbilical vein endothelial cells (HUVEC). The ED50 for this effect is 4.216-9.281 ng/mL (Routinely tested).
           
           

Inhibition assay shows that the proliferation effect of ActiveMax® Human VEGF165, Tag Free (MALS verified) (Cat. No. VE5-H4210) is inhibited by increasing concentration of anti-VEGF mAb (Avastin). The concentration of VEGF165 used is 20 ng/mL. The ED50 is 0.065-0.229 μg/mL (Routinely tested).
