It is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation.  IL-2\/IL-2R signaling is required for T-cell proliferation and other fundamental functions that are essential for the immune response.  IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine-activated killer cells, monocytes, macrophages and oligodendrocytes.","brand":"ELK Biotechnology","offers":[{"title":"10ug","offer_id":50413831586072,"sku":"EPT011","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_8787cdf5-0f22-41b1-b611-40d1e1212e02.jpg?v=1751163465","url":"https:\/\/danabiosci.com\/products\/ept011","provider":"Dana Bioscience","version":"1.0","type":"link"}
