Free Triiodothyronine (fT3) ELISA Kit

FT3 ELISA Kit employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with an antibody specific to fT3. Standards or samples are added to the appropriate microtiter plate wells with Biotin-conjugated fT3. A competitive inhibition reaction is launched between fT3 (Standards or samples) and Biotin-conjugated fT3 with the pre-coated antibody specific for fT3. The more amount of fT3 in samples, the less antibody bound by Biotin-conjugated fT3. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Substrate solution is added to the wells and the color develops in opposite to the amount of fT3 in the sample. The color development is stopped and the intensity of the color is measured.
