描述
PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Pembrolizumab has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled Human CD279 antigen and then pipetted into the wells. Anti-Pembrolizumab Neutralizing Antibody in the sample competitively binds to Pembrolizumab with the biotin-labeled Human CD279 antigen. 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 Anti-Pembrolizumab Neutralizing Antibody bound in the initial step. The color development is stopped and the intensity of the color is measured.

精准度
Intra-Assay Precision (Precision within an assay): <20%
Three samples of known concentration were tested sixteen times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays): <20%
Three samples of known concentration were tested in twenty four separate assays to assess inter-assay precision.
