product should be in buffers containing protein such as 0.1% bovine serum albumin (BSA).

Nota de análise

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).
