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\u003ch3\u003eTarget background\u003c\/h3\u003e\u003cp\u003eAlternative names include KLK3; APS; KLK2A1; hK3; Kallikrein-3; Kallikrein-Related Peptidase 3; Gamma-seminoprotein.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56179913654612,"sku":"ABM47756","price":284.4,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56179913687380,"sku":"ABM47755","price":407.05,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56179913720148,"sku":"ABM47757","price":1731.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK011ES-b-1.jpg?v=1781973341","url":"https:\/\/www.abmium.com\/products\/elk-elk011es-easystep-human-psa-prostatespecific-antigen-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
