The microtiter plate provided in this kit has been pre-coated with E1S. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to E1S. 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 E1S in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"ELK Bio","offers":[{"title":"48T","offer_id":43212252512435,"sku":"ELK7928-48","price":371.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":43212252545203,"sku":"ELK7928-96","price":526.4,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200786948275,"sku":"ELK7928-5x96","price":2237.2,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_990bd7df-737e-44cc-b118-329d6a902dc5.png?v=1767063783","url":"https:\/\/afsbio.com\/products\/e1s-estrone-sulfate-elisa-kit-elk7928","provider":"AFSBio Inc.","version":"1.0","type":"link"}
