The microtiter plate provided in this kit has been pre-coated with an antibody specific to Cattle ET-1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Cattle ET-1. 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 Cattle ET-1, 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 Cattle ET-1 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 ET1; PPET1; Preproendothelin-1; Big endothelin-1; EDN1.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56184412012884,"sku":"ABM80732","price":366.17,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56184412045652,"sku":"ABM80731","price":522.59,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56184412078420,"sku":"ABM80733","price":2221.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK8839-b-1.jpg?v=1782018558","url":"https:\/\/www.abmium.com\/products\/elk-elk8839-cattle-et-1-endothelin1-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
