It is produced not only by mature T lymphocytes on stimulation but also constitutively by certain T-cell lymphoma cell lines. IL-2 expression in mature thymocytes and T cells has been found to be tightly controlled by monoallelic expression. It can act as a growth hormone for both B and T lymphocytes. IL-2 has a well documented role in induction of pruritus, furthermore, it has been found to be higher in pruritic lesions of psoriasis compared to non-pruritic ones.\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-2 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-IL-2 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 substrateswere 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-2 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of IL-2 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 15.6 pg\/ml - 1000 pg\/ml\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e \u0026lt; 1 pg\/ml","brand":"Biospes","offers":[{"title":"96T","offer_id":50409022554392,"sku":"BEK1099","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/Biospes-logo_5592237b-34bf-4f7d-acac-c2e171d6b72d.jpg?v=1750988442","url":"https:\/\/danabiosci.com\/products\/bek1099","provider":"Dana Bioscience","version":"1.0","type":"link"}
