The microtiter plate provided in this kit has been pre-coated with DHEA-S protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to DHEA-S. 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 DHEA-S in the samples is then determined by comparing the OD of the samples to the standard curve.","brand":"ELK Biotechnology","offers":[{"title":"96T","offer_id":50410623598872,"sku":"ELK8370","price":558.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_b7dd9b28-656d-41d5-b239-95b20bc9018a.jpg?v=1751051792","url":"https:\/\/danabiosci.com\/products\/elk8370","provider":"Dana Bioscience","version":"1.0","type":"link"}
