The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CA19-9. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CA19-9. 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 CA19-9, 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 CA19-9 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":43211564253363,"sku":"ELK1198-48","price":371.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43211564286131,"sku":"ELK1198-96","price":526.4,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200710959283,"sku":"ELK1198-5x96","price":2237.2,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_becdc654-068a-4dee-9184-d55175d93a14.png?v=1767062014","url":"https:\/\/afsbio.com\/products\/human-ca19-9-carbohydrate-antigen-19-9-elisa-kit-elk1198","provider":"AFSBio Inc.","version":"1.0","type":"link"}
