The microtiter plate provided in this kit has been pre-coated with Human E2 antigen, and the Human E2 standard plate wells that pre-coated using protein-related techniques are provided separately. Standard\/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human E2 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 E2 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 17B-Estradiol; Oestradiol; Beta-Estradiol.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56179929481556,"sku":"ABM48026","price":366.17,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56179929514324,"sku":"ABM48025","price":522.59,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56179929547092,"sku":"ABM48027","price":2221.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK020ES-b-1.jpg?v=1781973474","url":"https:\/\/www.abmium.com\/products\/elk-elk020es-easystep-human-e2-estradiol-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
