Product Description specificalIntended Uses: For the quantitative detection of Human Free Tri-iodothyronine Indes (fT3) concentration in serum, plasma, cell culture supernates and other biological fluids.
Principle of the Assay: This assay employs the competitive inhibition enzyme immunoassay technique. An antibody specific for fT3 has been pre-coated onto a microplate. Standards or samples and a biotin-conjugated antibody specific for fT3 are pipetted into the wells. A competitive inhibition reaction is launched between fT3 (Standards or samples) and biotin-conjugated fT3 with the pre-coated antibody specific for fT3. After washing, streptavidin 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 fT3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
