EasyStep Human T4(Thyroxine) ELISA Kit

EasyStep Human T4(Thyroxine) ELISA Kit is an ELK Biotechnology ELISA kit for research measurement of EasyStep Human T4.

Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human T4 antigen, and the Human T4 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 T4 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 T4 in the samples is then determined by comparing the OD of the samples to the standard curve.

Target background

Alternative names include 3,5,3',5'-Tetraiodothyronine; L-Thyroxine; Levothyroxine.
