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.\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"ELK Bio","offers":[{"title":"48T","offer_id":43211435245747,"sku":"ELK054ES-48","price":576.8,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43211435278515,"sku":"ELK054ES-96","price":823.2,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200472899763,"sku":"ELK054ES-5x96","price":3498.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_864faea6-ce6d-40af-94b4-d163d60ccc20.png?v=1767060577","url":"https:\/\/afsbio.com\/products\/easystep-human-t4-thyroxine-elisa-kit-elk054es","provider":"AFSBio Inc.","version":"1.0","type":"link"}
