Specification

• 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.
