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\u003ch3\u003eTarget background\u003c\/h3\u003e\u003cp\u003eAlternative names include CA72-4.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56179975356756,"sku":"ABM49052","price":284.4,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56179975389524,"sku":"ABM49051","price":407.05,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56179975422292,"sku":"ABM49053","price":1731.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK0545-b-1.jpg?v=1781974723","url":"https:\/\/www.abmium.com\/products\/elk-elk0545-human-ca72-4-carbonhydrate-antigen-72-4-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
