This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with α-Endorphin. α-Endorphin in the sample or standard competes with a fixed amount of biotin-labeled α-Endorphin for sites on a pre-coated antibody specific to α-Endorphin. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. 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. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of α-Endorphin in the sample. The concentration of the target substance is inversely proportional to the OD450 value.\u003c\/p\u003e","brand":"Fine Test","offers":[{"title":"96 wells","offer_id":49020968927460,"sku":"EH4308","price":520.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/6238\/8964\/files\/EH4308_bd668376-7476-4152-bff6-e5353558ba53.jpg?v=1779894558","url":"https:\/\/www.ardentbio.com\/products\/human-alpha-endorphin-alpha-endorphin-elisa-kit-5202026","provider":"Ardent Bio LLC","version":"1.0","type":"link"}
