The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CA72-4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CA72-4. 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 CA72-4, 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 CA72-4 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":43211503272115,"sku":"ELK0545-48","price":448.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43211503304883,"sku":"ELK0545-96","price":641.2,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200637460659,"sku":"ELK0545-5x96","price":2725.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_4d0fe256-d5ab-4232-9613-74201e3dc684.png?v=1767060573","url":"https:\/\/afsbio.com\/products\/human-ca72-4-carbonhydrate-antigen-72-4-elisa-kit-elk0545","provider":"AFSBio Inc.","version":"1.0","type":"link"}
