The microtiter plate provided in this kit has been pre-coated with Cattle T4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Cattle T4. 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 Cattle 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":43212823167155,"sku":"ELK9521-48","price":371.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43212823199923,"sku":"ELK9521-96","price":526.4,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200825417907,"sku":"ELK9521-5x96","price":2237.2,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_7265608f-083c-409e-bfd5-22858902fd55.png?v=1767064993","url":"https:\/\/afsbio.com\/products\/cattle-t4-thyroxine-elisa-kit-elk9521","provider":"AFSBio Inc.","version":"1.0","type":"link"}
