Biochem/physiol Actions
Cytokine with anti-viral, anti-proliferative, immunoregulatory, and proinflammatory activities.
Interferon β belongs to the type 1 interferon family pf proteins. It is also needed for the inhibition of tumor cell growth via cell death, S-phase increase and mediating differentiation. It is also important for bone homeostasis.
Physical form
Lyophilized from phosphate buffered saline (PBS) containing 125 mM trehalose.
Analysis Note
The biological activity is determined in the cytopathic effect inhibition assay using rat epithelial-like (RATEC) cells with vesicular stomatitis virus (VSV). The cytopathic effect of 50% is produced with approximately 1 unit/ml interferon. Since there is no international rat interferon β standard, units are determined with respect to the NIH international standard reference for mouse interferon α/β.
