The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CYFRA21-1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CYFRA21-1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human CYFRA21-1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 CYFRA21-1 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":43211602559155,"sku":"ELK1967-48","price":448.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43211602591923,"sku":"ELK1967-96","price":641.2,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200716497075,"sku":"ELK1967-5x96","price":2725.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_8efad0f8-e589-4015-971a-90168e927863.png?v=1767062226","url":"https:\/\/afsbio.com\/products\/human-cyfra21-1-cytokeratin-fragment-antigen-21-1-elisa-kit-elk1967","provider":"AFSBio Inc.","version":"1.0","type":"link"}
