The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse CA19-9. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse 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 Mouse 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 Mouse CA19-9 in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e","brand":"Elk Biotechnology","offers":[{"title":"96 wells","offer_id":48862943543524,"sku":"ELK9717MS","price":488.8,"currency_code":"USD","in_stock":true},{"title":"48 wells","offer_id":48862943576292,"sku":"ELK9717MS","price":344.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/6238\/8964\/files\/ELK9717MS-b-1.jpg?v=1777676333","url":"https:\/\/www.ardentbio.com\/products\/mouse-ca19-9-carbohydrate-antigen-19-9-elisa-kit-small-sample-4292026","provider":"Ardent Bio LLC","version":"1.0","type":"link"}
