It is produced by mast cells, T cells and bone marrow stromal cells. IL-4 signals through two receptor complexes: theIL4Rα\/common γ chain and the IL4Rα-IL-13 Rα1 receptor complex. IL-4 regulates T cell and B cell proliferation, survival and gene expression. IL-4 also induces IgG and IgE class switching, and the upregulation of MHC-II production.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5μg","offer_id":42882254078131,"sku":"BK0244-5","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"25μg","offer_id":42882254110899,"sku":"BK0244-25","price":691.77,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_63695bbc-f32e-4391-9e84-1fccbcabab9e.jpg?v=1702050146","url":"https:\/\/afsbio.com\/products\/recombinant-il-4-his-rat-bk0244","provider":"AFSBio Inc.","version":"1.0","type":"link"}
