The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human HE4, and the Human HE4 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 HE4. After TMB substrate solution is added, only those wells that contain Human HE4 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 HE4 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 Epididymis Protein 4; dJ461P17.6 ; EDDM4 ; epididymal protein 4 ; Epididymal secretory protein E4 ; Epididymis specific whey acidic protein type four disulfide core ; HE 4 ; Major epididymis specific protein E4 ; Major epididymis-specific protein E4 ; MGC57529 ; Putative protease inhibitor WAP5 ; WAP 5 ;.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56179920470356,"sku":"ABM47861","price":366.17,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56179920503124,"sku":"ABM47860","price":522.59,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56179920535892,"sku":"ABM47862","price":2221.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK014ES-b-1.jpg?v=1781973399","url":"https:\/\/www.abmium.com\/products\/elk-elk014es-easystep-human-he4-epididymal-protein-4-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
