The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human sTFR, and the Human sTFR standard plate wells that pre-coated using protein-related techniques are provided separately. Standard\/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human sTFR. After TMB substrate solution is added, only those wells that contain Human sTFR and HRP-conjugated antibody will exhibit a change in color. 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 sTFR in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/strong\u003e.
