The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human Ab1-40. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Ab1-40. 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 Ab1-40, 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 Ab1-40 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 Amyloid Beta Peptide 1-40.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56180561576276,"sku":"ABM56993","price":284.4,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56180561609044,"sku":"ABM56992","price":407.05,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56180561641812,"sku":"ABM56994","price":1731.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK1492-b-1.jpg?v=1781984593","url":"https:\/\/www.abmium.com\/products\/elk-elk1492-human-ab1-40-amyloid-beta-peptide-1-40-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
