Physical form
Frozen liquid in 50 mM NaOAc, pH 5.5, containing 0.1% BSA.
Storage and Stability
After receipt, this product should be kept at -70°C or below for retention of full activity.
Thaw product vial by incubation cold tap water until just thawed. Thawed IFNβ should be
stored in working aliquots at -70°C for up to six months. Avoid multiple freeze/thaw cycles.
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).

Analysis Note
Specific Activity: Determined by assaying inhibition of virus-induced cytopathic effect.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 human interferon beta (Hu-IFNbeta) provided by the National Institutes of Health.Unit of activity measured on VERO cells with vesicular stomatitis virus (VSV).
