The microtiter plate provided in this kit has been pre-coated with Rat fT4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat fT4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added 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 Rat fT4 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":45200702046387,"sku":"ELK11233-48","price":448.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":45200702079155,"sku":"ELK11233-96","price":641.2,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200702111923,"sku":"ELK11233-5x96","price":2725.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_1e9db238-9650-4a70-b539-8304eaa16e10.png?v=1767061858","url":"https:\/\/afsbio.com\/products\/rat-ft4-free-thyroxine-elisa-kit-elk11233","provider":"AFSBio Inc.","version":"1.0","type":"link"}
