Specifications/Features
This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for IL21 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IL21 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL21 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 IL21 bound in the initial step. The color development is stopped and the intensity of the color is measured.
