Product overview
Abcam’s Thyroxine (T4) in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of T4 in serum and plasma.
A 96-well plate has been precoated with anti-Thyroxine (T4) antibodies (solid-phase). Samples and the Thyroxine (T4)-HRP conjugate are added to the wells, where Thyroxine (T4) in the sample competes with the added Thyroxine (T4)-HRP conjugate for antibody binding. After incubation, the wells are washed to remove unbound material and TMB substrate is then added which is catalyzed by HRP to produce blue coloration. The reaction is terminated by addition of Stop Solution which stops the color development and produces a color change from blue to yellow. The intensity of signal is inversely proportional to the amount of Thyroxine (T4) in the sample and the intensity is measured at 450 nm.
