The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL-40. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL-40. 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 IL-40, 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 IL-40 in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/strong\u003e. After binding and washing, signal is converted to concentration using a standard curve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSample types\u003c\/strong\u003e: serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection range\u003c\/strong\u003e: 0.32-20 ng\/mL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity\/LoD\u003c\/strong\u003e: 0.13 ng\/mL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssay time\u003c\/strong\u003e: 3.5h\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELK Biotechnology","offers":[{"title":"96 T","offer_id":52966410355053,"sku":"ELK0969MS-96T","price":595.4,"currency_code":"USD","in_stock":true},{"title":"48 T","offer_id":52966410387821,"sku":"ELK0969MS-48T","price":416.0,"currency_code":"USD","in_stock":true},{"title":"96 T X 5","offer_id":52966410420589,"sku":"ELK0969MS-96TX5","price":2531.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/1h1qbq4v21p4717oo1b_df6887ba-2752-434e-b4c5-588429da325e.jpg?v=1771848474","url":"https:\/\/www.ebiohippo.com\/products\/human-il-40-interleukin-40-microsample-elisa-kit-bhe15212354","provider":"BioHippo","version":"1.0","type":"link"}
