Tech Info & Data



Interferons (IFNs) are a family of mammalian cytokines produced by macrophages, neutrophils, dendritic cells and other somatic cells in response to viruses and pathogens. IFN-Beta is classified as a type I IFN and is produced by fibroblast and a variety of cell types in response to viral challenge. Although all type I IFNs bind to the same type I IFN receptor complex, studies have shown that IFN-Beta signals differently than IFN-Alpha. Furthermore, it has been shown that IFN-Beta exerts preferential induction of apoptotic effect on melanoma cells. These findings, along with the therapeutic use of IFN-Beta in Multiple Sclerosis and hepatitis C, make further understanding of IFN-Beta biological activities an important area of research. 

The mammalian expressed mouse IFN-Beta protein is designed to provide scientists with a highly active recombinant protein that closely resembles native mouse IFN-Beta.
