The microtiter plate provided in this kit has been pre-coated with F-E3. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to F-E3. 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 F-E3 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 F-E3; Free Estriol.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56184700961108,"sku":"ABM83150","price":236.41,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56184700993876,"sku":"ABM83149","price":334.17,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56184701026644,"sku":"ABM83151","price":1420.22,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK9646-b-1.jpg?v=1782024660","url":"https:\/\/www.abmium.com\/products\/elk-elk9646-f-e3-free-estriol-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
