The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat IL-2sRa\/CD25. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat IL-2sRa\/CD25. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat IL-2sRa\/CD25, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 Rat IL-2sRa\/CD25 in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e","brand":"Elk Biotechnology","offers":[{"title":"96 wells","offer_id":48863045091556,"sku":"ELK5694MS","price":595.4,"currency_code":"USD","in_stock":true},{"title":"48 wells","offer_id":48863045124324,"sku":"ELK5694MS","price":416.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/6238\/8964\/files\/ELK5694MS-b-1.jpg?v=1777676195","url":"https:\/\/www.ardentbio.com\/products\/rat-il-2sra-cd25-soluble-interleukin-2-receptor-alpha-chain-elisa-kit-small-sample-4292026","provider":"Ardent Bio LLC","version":"1.0","type":"link"}
