The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human PSA, and the Human PSA standard plate wells that pre-coated using protein-related techniques are provided separately. Standard\/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Human PSA. After TMB substrate solution is added, only those wells that contain Human PSA and HRP-conjugated antibody 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 PSA in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUniProt ID\u003c\/b\u003e:\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48644858642532,"sku":"ELK011ES","price":566.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_0b64ea5b-8385-486f-8115-e36268a85212.jpg?v=1782659232","url":"https:\/\/www.genebiosystems.com\/en-gb\/products\/easystep-human-psa-prostatespecific-antigen-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
