General description

IFN β (interferon β) is from the type 1 interferon family of cytokines.

Biochem/physiol Actions

In presence of virus infection, IFN β (interferon β) is upregulated and plays a crucial role in innate antiviral response. It is also important for anti-inflammatory effects.

Cytokine with anti-viral, anti-proliferative, immunoregulatory, and proinflammatory activities.

Physical form

Solution in 20 mM HEPES, pH 6.0, 0.5 M NaCl, 6% glycerol, and 0.1% bovine serum albumin.

Analysis Note

The biological activity is determined in the cytopathic effect inhibition assay using mouse L929 cells with encephalomyocarditis virus. The cytopathic effect of 50% is produced with approximately 1 unit/ml interferon. The units are determined with respect to NIH international standard reference for mouse interferon β.
