Product Description Bevacizumab, with the brand name Avastin, is a humanized monoclonal antibody of IgG1 isotype. It targets the vascular endothelial growth factor A (VEGF-A), preventing its activation of VEGF receptor and inhibiting malignant cell growth and blood vessel formation. Bevacizumab is approved for the treatment of patients with cervical cancer, metastatic colorectal cancer, primary peritoneal cancer and so on.
GenScript has developed and validated the Bevacizumab Pharmacokinetic ELISA Kit for quantitative measurement of Bevacizumab in cynomolgus monkey serum and plasma, following the ICH M10 and the FDA bioanalytical method validation guidance for industry. Its precision, accuracy, dilutional linearity, specificity, selectivity, stability, and hook effect were acceptable according to the guidances [1-4]. The Bevacizumab ELISA kit is a validated tool for quantifying both Bevacizumab and its biosimilars in biological matrices, facilitating drug research and development.

Assay Principle Bevacizumab Pharmacokinetic ELISA Kit utilizes a sandwich ELISA assay format with a pair of anti-idiotypic monoclonal antibodies for capture and detection. When standards or samples are added to the capture plate, the Bevacizumab in the sample can be captured on the plate coated with the Bevacizumab capture antibody. The Biotin Anti-Bevacizumab Antibody is then added to interact with the Bevacizumab bound on the plate. Streptavidin-Horseradish Peroxidase conjugate (Streptavidin-HRP) is added to interact with the Biotin Anti-Bevacizumab Antibody. After the washing steps, the addition of 3,3',5,5'-Tetramethylbenzidine solution (TMB Solution) leads to the development of a blue color. The reaction is stopped by adding Stop Solution, causing the color to change from blue to yellow. The intensity of the resulting color can be measured at 450 nm and 630 nm using a microplate reader. The quantity of Bevacizumab in the sample is accurately determined by comparing it against a Bevacizumab standard curve.
