IFN-beta (Interferon-beta) is a cytokine that is produced by fibroblasts and pathogen-exposed dendritic cells, macrophages, and endothelial cells. It signals through the heterodimeric IFN-alpha/beta Receptor. IFN-beta-deficient mice show increased susceptibility to experimental autoimmune encephalomyelitis (EAE), a disease model of human multiple sclerosis (MS). Furthermore, IFN-beta has been shown to suppress the Th17 cell response in both MS and EAE and has commonly been used as a treatment for MS.

Recommended Usage
Neutralization
One neutralization unit is the amount of antiserum required to neutralize one unit of
human interferon beta (Hu-IFN-beta ) to a 50% endpoint. Interferon was titrated with the use of the cytopathic effect inhibition
assay as described [Rubinstein, S., Familletti, P.C., and Pestka, S. (1981) "Convenient Assay for Interferons," J. Virol. 37,
755-758; Familletti, P.C., Rubinstein, S., and Pestka, S. (1981) "A Convenient and Rapid Cytopathic Effect Inhibition
Assay for Interferon," in Methods in Enzymology, Vol. 78 (S. Pestka, ed.), Academic Press, New York, 387-394]. In this
antiviral assay for interferon about 1 unit/ml of interferon is the quantity necessary to produce a cytopathic effect of 50%.
The units are determined with respect to the international reference standard for Hu-IFN-beta provided by the National
Institutes of Health [see Pestka, S. (1986) "Interferon Standards and General Abbreviations," in Methods in Enzymology
(S. Pestka, ed.), Academic Press, New York 119, 14-23]. This material is prepared specifically for effective neutralization
of Hu-IFN-beta.
Formulation, Preparation, and Storage
Formulation
Neat serum.
Shipping
The product is shipped with dry ice or equivalent. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage
After receipt, the product may be stored at -20°C for short-term use (≤ 6 months). For
long-term storage, we recommend storing the product at -70°C or below for retention of full activity. When thawing, the
contents of the tube should be apportioned in separate tubes so that freezing and thawing is kept to a minimum.
Refreezing should be done on dry ice or in a dry ice/alcohol bath. Further dilution of the product should be in buffers
containing protein such as 0.1% bovine serum albumin (BSA).
