The microtiter plate provided in this kit has been pre-coated with VA protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to VA. 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 VA 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":50410743988504,"sku":"ELK9582","price":558.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_bbe1b823-c632-4bca-984c-2fb7feb0307c.jpg?v=1751055002","url":"https:\/\/danabiosci.com\/products\/elk9582","provider":"Dana Bioscience","version":"1.0","type":"link"}
