It can increase production and mobilization of eosinophils and CD34+ progenitors from the bone marrow. IL-5 plays an important role in inducing cell-mediated immunity against parasitic infections and certain tumors. IL-5 also promotes differentiation of basophils and primes them for histamine and leukotriene release.Recombinant Human IL-5 is homodimeric protein with molecular weight ranging from 29 to 35 kDa due to glycosylation.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882256666803,"sku":"BK0249-10","price":256.94,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882256699571,"sku":"BK0249-50","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_bcc12e7c-88f2-4c35-ab68-8f158e89ba55.jpg?v=1702050155","url":"https:\/\/afsbio.com\/products\/recombinant-il-5-human-cho-expre-ssed-bk0249","provider":"AFSBio Inc.","version":"1.0","type":"link"}
