This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti IL-3 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with IL-3 bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of IL-3 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.\u003c\/p\u003e","brand":"Fine Test","offers":[{"title":"96 wells","offer_id":49027844145380,"sku":"ER0040","price":455.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/6238\/8964\/files\/ER0040_0222df6d-16a3-469f-89b6-2598a335769c.jpg?v=1779905888","url":"https:\/\/www.ardentbio.com\/products\/rat-il-3-interleukin-3-elisa-kit-5202026","provider":"Ardent Bio LLC","version":"1.0","type":"link"}
