Human Estradiol (E2) EasyStep ELISA Kit

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human E2 antigen, and the Human E2 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 E2 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 E2 in the samples is then determined by comparing the OD of the samples to the standard curve.
