The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human F-PSA. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human F-PSA. 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 Human F-PSA, 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 Human F-PSA 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":50410769285400,"sku":"ELK9865","price":558.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_91581cc3-63c0-4765-94eb-1990fa42abc7.jpg?v=1751055820","url":"https:\/\/danabiosci.com\/products\/elk9865","provider":"Dana Bioscience","version":"1.0","type":"link"}
