Background: Tremelimumab (formerly ticilimumab, CP-675,206) is a fully human monoclonal antibody against CTLA-4. It is an immune checkpoint blocker. Cytotoxic T lymphocytes (CTLs) can recognize and destroy cancer cells. However, there is also an inhibitory mechanism (immune checkpoint) that interrupts this destruction. Tremelimumab turns off this inhibitory mechanism and allows CTLs to continue to destroy the cancer cells. Intended Use: For Estimation of Tremilimumab in human serum and plasma. Please note the kit has not been optimized to be used for any other animal species. Should you require a specific sera tested, please connect with us at sales@krishgen.com for optimization. Principle: The method employs the quantitative enzyme immunoassay technique. Standards or samples are pipetted into microwells pre-coated with Anti- Tremelimumab antibody and Tremelimumab present in the sample and standards are bound by Anti- Tremelimumab antibody. In the second step, Detection antidody is added and incubated. In the third step, a HRP conjugate is pipetted and incubated. Free HRP conjugate will be removed by washing. Addition of TMB substrate will develop blue color and intensity of blue colour in wells is proportional to the concentration of Tremelimumab present in standard or sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
