Recombinant IFN-β, Human

SKU: orb1494646

Description

Interferon-beta (IFN-β), acting via STAT1 and STAT2, is known to upregulate and downregulate a wide variety of genes, most of which are involved in the antiviral immune response. 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.
