Human fT3 (Free Triiodothyronine) ELISA kit

This kit applies competitive inhibition ELISA method for the quantitative detection of fT3 (Free Triiodothyronine) in human samples. The microtiter plate provided in this kit has been pre-coated with Human fT3 protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human fT3. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ±10nm. The concentration of Human fT3 in the samples is then determined by comparing the OD of the samples to the standard curve.
