{"product_id":"new-product-228336","title":"IL4 polyclonal antibody","description":"\u003cp\u003eInterleukin-4 (IL-4), also designated B cell stimulatory factor-1, is a glycosylated cytokine secreted by activated T lymphocytes, basophils and mast cells. The secreted IL-4 protein promotes the growth and differentiation of cells that participate in immune defense by favoring such events as the expansion of the Th2 lineage relative to Th1 cells. These T helper cell subsets are defined by their pattern of cytokine secretion: Th1 cells secrete IL-2, TNFβ and IFN-γ, while Th2 cells secrete IL-4, IL-5 and IL-10. Another key immunological function of IL-4 is to induce immunoglobulin class switching. IL-4 has been shown to induce the production of IgE and enhance IgG4 secretion by B cells, but suppress the production of IgM, IgA, IgG1, IgG2, and IgG3.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human","offer_id":47662347419928,"sku":"BS70684","price":408.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_86e2cd92-b2f6-49b8-8858-125393b0a9bf.jpg?v=1707484118","url":"https:\/\/danabiosci.com\/products\/new-product-228336","provider":"Dana Bioscience","version":"1.0","type":"link"}
