Anti Bevacizumab ELISA
Bevacizumab is a recombinant Human IgG;κ monoclonal antibody specific for all human vascular endothelial growth factor A (VEGF-A) isoforms. Additionally, Bevacizumab binds to and neutralizes all human VEGF-A isoforms an bioactive proteolytic fragments, but not mouse or rat VEGF.
Intended Use: This Anti Bevacizumab ELISA is used as an analytical tool for qualitative laboratory screening of presence or absence of antibodies to Bevacizumab in serum and plasma. The Anti Bevacizumab is for research use only. Not for diagnostic or therapeutic procedures.
Principle: The method employs the qualitative sandwich enzyme immunoassay technique. A commercially available AVASTIN is pre-coated onto microwells. Samples and Controls are pipetted into microwells and antibodies to human Bevacizumab present in the sample are bound by the capture antibody. Then, a HRP (horseradish peroxidase) conjugated Bevacizumab is pipette and incubated simultaneously with samples. After washing microwells in order to remove any non specific binding, the ready to use substrate solution (TMB) is added to microwells and color develops proportionally to the amount of antibodies to AVASTIN in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
The kit uses a sandwich ELISA format to quantify the target cytokine between two layers of antibodies (i.e. capture and detection antibody). The cytokine to be measured contains at least two antigenic epitope capable of binding to antibody, since at least two antibodies act in the sandwich. The advantage of Sandwich ELISA is that the sample does not have to be purified before analysis, and the assay can be very sensitive upto pg/ml levels (more sensitive than direct or indirect ELISA). A highly efficient blocking and stabilizing proprietary solution is used in the kit. All KRISHGEN cytokine ELISA kits are optimized to give the best possible noise:signal ratios.
