Members of the cytokine IL-20 subfamily form an important link between the immune system and epithelial tissues due to the fact that receptors for these cytokines are highly expressed on epithelial cells and are almost exclusively produced by cells of the immune system. IL-20 requires an IL-β-subunit receptor (IL-20RB) for signaling, which can form a functional heterodimeric receptor with either the α-subunit of the IL-20 receptor (IL-20RA) or the α1-subunit of the IL-22 receptor (IL-22RA1). Both of these receptor variants allow efficient IL-20 signaling.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePrinciple of the Assay:\u003c\/strong\u003e This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-IL-20 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-IL-20 polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the IL-20 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of IL-20 can be calculated.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStorage and Expiration:\u003c\/strong\u003e Store at 2-8℃ for 6 months, or at -20℃ for 12 months.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRange:\u003c\/strong\u003e 62.5 pg\/ml - 4000 pg\/ml\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e \u0026lt; 10 pg\/ml","brand":"Biospes","offers":[{"title":"96T","offer_id":50409047720216,"sku":"BEK1305","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/Biospes-logo_3f3fe2f1-94eb-4fba-86b3-2ddb791b72f8.jpg?v=1750988874","url":"https:\/\/danabiosci.com\/products\/bek1305","provider":"Dana Bioscience","version":"1.0","type":"link"}
