Description
Principle of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for TS has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TS present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TS is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TS bound in the initial step. The color development is stopped and the intensity of the color is measured
