Report

 

活性(Bioactivity)-ELISA

Bevacizumab ELISA

Detection of bevacizumab by bridging ELISA in serum. Immobilized Anti-Bevacizumab Antibody (AY10) (Cat. No. BEB-Y10) at 2 μg/mL, add increasing concentrations of bevacizumab (10% human serum) and then add Biotinylated Anti-Bevacizumab Antibody (AY13) (Cat. No. BEB-BY13) at 2 μg/mL. Detection was performed using HRP-conjugated streptavidin with a sensitivity of 0.4 μg/mL.

Protocol

Bevacizumab ELISA

Immobilized Bevacizumab at 1 μg/mL (100 μL/well) can bind Anti-Bevacizumab Antibody (AY10) (Cat. No. BEB-Y10) with a linear range of 0.39-25 ng/mL.

Protocol

Bevacizumab ELISA

Immobilized Bevacizumab at 2 μg/mL (100 μL/well) can bind pre-mixed Anti-Bevacizumab Antibody (AY10) (Cat. No. BEB-Y10) and Biotinylated Human VEGF165, His,Avitag (Cat. No. VE5-H82Q0) with a inhibition rate of 81%.

Protocol

 

背景(Background)

A recombinant humanized monoclonal IgG1 antibody that binds to and inhibits the biologic activity of human vascular endothelial growth factor (VEGF). Bevacizumab contains human framework regions and the complementarity-determining regions of a murine antibody that binds to VEGF. Bevacizumab is produced in a Chinese Hamster Ovary mammalian cell expression system in a nutrient medium containing the antibiotic gentamicin and has a molecular weight of approximately 149 kilodaltons.
