Interferon induces a variety of effects on target cells including antiviral, antiproliferative, and immunomodulatory activities. Interferon alpha-2b can either inhibit or enhance immune cell activity within the tightly regulated microenvironment of inflammation, depending upon the concentration of the cytokine and the activation stage of the cell. Interferon alpha-2b was expressed in E. coli and purifed by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer. Alternative Names: IFN alphab -2, Interferon a-2b protein, IRF-2-binding protein 1 protein, IFN alphab -2 protein, IFN alphab 2 protein, IRF2BP1 protein, interferon regulatory factor 2 binding protein 1 protein, IRF-2BP1 protein, IRF-2BP1, IFN alphab 2, DKFZP434M154 protein, IFN alpha2b, Interferon regulatory factor 2-binding protein 1 protein
