Product Description specificalPrinciple of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for 20SP has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any 20SP present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for 20SP 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 20SP bound in the initial step. The color development is stopped and the intensity of the color is measured.
