• Description: IFN-β is a type I cytokine produced in response to exposure to viruses or double-stranded RNAs. It is also induced by other cytokines, such as TNF and IL-1. It is involved in the regulation of non-specific humoral immune responses and immune responses to viral infections, and thus exhibits anti-viral, anti-proliferative, and immunomodulating properties. The biological activity of IFN-β, unlike IFN-α, is strictly species-specific and will not be active across species.

• Bio-activity: Reported as IU/mg on a lot-specific basis using a viral resistance assay
• Molecular Mass: 22500
• Purity: ≥98% by SDS-PAGE
