It is a member of Type I IFNs, which include IFN-α, -β, τ, and –ω. IFN-β plays an important role in inducing non-specific resistance against a broad range of viral infections. It also affects cell proliferation and modulates immune responses.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5μg","offer_id":42882262007987,"sku":"BK0307-5","price":256.94,"currency_code":"CAD","in_stock":true},{"title":"25μg","offer_id":42882262040755,"sku":"BK0307-25","price":813.32,"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_9aaec638-e508-4767-b6a1-5f688a388e0c.jpg?v=1702050276","url":"https:\/\/afsbio.com\/products\/recombinant-ifn-%ce%b2-human-bk0307","provider":"AFSBio Inc.","version":"1.0","type":"link"}
