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).

Physical form
Frozen liquid in 50 mM NaOAc, pH 5.5, containing 0.1% BSA.
Preparation Note
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).

Viral infection of the heart is a common but underappreciated cause of heart failure. Viruses can cause direct cardiac damage by lysing infected cardiomyocytes. Inflammatory immune responses that limit viral replication can also indirectly cause damage during infection, making regulatory

During DNA virus infections, detection of cytosolic DNA by the cGAS-STING pathway leads to activation of IFN-β. Kaposi's Sarcoma Herpesvirus (KSHV), an oncogenic DNA virus, is the etiological agent of Kaposi's Sarcoma, an endothelial cell (EC)-based tumor. To investigate the

The mechanism of tumor-selective replication of oncolytic measles virus (MV) is poorly understood. Using a stepwise model of cellular transformation, in which oncogenic hits were additively expressed in human bone marrow-derived mesenchymal stromal cells, we show that MV-induced oncolysis increased
