Biochem/physiol Actions

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

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.

Interferon therapies suffer from a relatively short half-life of the products in circulation. To address this issue we investigated the effects of polyethylene glycol modification (PEGylation) on the pharmacokinetic properties of human interferon (IFN)-beta-1a. PEGylation with a linear 20-kDa PEG

Cell-based therapy for cancer is a promising new field. Among cell types that can be used for this purpose, mesenchymal stem cells (MSCs) appear to hold great advantage for reasons including easier propagation in culture, possible genetic modification to express

Interferon (IFN)-beta has significant immunomodulatory properties and has received much interest as a potentially therapeutic agent for rheumatoid arthritis (RA). Systemic IFN-beta treatment of patients with RA was not effective, probably because of pharmacokinetic issues. Therefore, we studied the effect

The production of type I interferons (IFNs) in response to viral infections is critical for antiviral immunity. However, IFN production is transient, and continued expression can lead to inflammatory or autoimmune diseases. Thus, understanding the mechanisms underlying the negative regulation
