It is a protein that in humans is encoded by the IL13 gene. Interleukin-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells.It is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils.","brand":"ELK Biotechnology","offers":[{"title":"10ug","offer_id":50413935460632,"sku":"EPT242","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/ELK_2d42838e-8621-4835-88df-53fb378bc17b.jpg?v=1751164175","url":"https:\/\/danabiosci.com\/products\/ept242","provider":"Dana Bioscience","version":"1.0","type":"link"}
