The microtiter plate provided in this kit has been pre-coated with Goat T4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Goat 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 Goat 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":43211526930611,"sku":"ELK0741-48","price":371.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43211526963379,"sku":"ELK0741-96","price":526.4,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200642113715,"sku":"ELK0741-5x96","price":2237.2,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_cb7588e9-ebe3-44cb-97f5-8d46a3f4efc8.png?v=1767060712","url":"https:\/\/afsbio.com\/products\/goat-t4-thyroxine-elisa-kit-elk0741","provider":"AFSBio Inc.","version":"1.0","type":"link"}
