The microtiter plate provided in this kit has been pre-coated with Human CA19-5. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CA19-5. 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 Human CA19-5 in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e\u003ch3\u003eTarget background\u003c\/h3\u003e\u003cp\u003eAlternative names include CA19-5.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56183497032020,"sku":"ABM75470","price":284.4,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56183497064788,"sku":"ABM75469","price":407.05,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56183497097556,"sku":"ABM75471","price":1731.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK7082-b-1.jpg?v=1782002785","url":"https:\/\/www.abmium.com\/products\/elk-elk7082-human-ca19-5-carbohydrate-antigen-19-5-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
