PRINCIPLE OF THE ASSAY
This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant human PD1 antigen has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Tislelizumab in the sample competitively binds to the pre-coated protein with biotin-labeled Tislelizumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Tislelizumab bound in the initial step. The color development is stopped and the intensity of the color is measured.
