The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human HLA-DRA. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human HLA-DRA. 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 HLA-DRA, 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 HLA-DRA in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e\n\n\u003cp\u003eUniProt ID: P01903\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"ELK Bio","offers":[{"title":"48T","offer_id":45199997894835,"sku":"ELK11289-48","price":448.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":45199997927603,"sku":"ELK11289-96","price":641.2,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45199997960371,"sku":"ELK11289-5x96","price":2725.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_1fdb4550-0723-4d23-9d5a-38e90bbf9905.png?v=1767030289","url":"https:\/\/afsbio.com\/products\/human-hla-dra-hla-class-ii-histocompatibility-antigen-dr-alpha-chain-elisa-kit-elk11289","provider":"AFSBio Inc.","version":"1.0","type":"link"}
