[Structural characteristics of immune interferon in mice]

In the present study we have analyzed the biochemical characteristics of murine immune interferon (IFN-y). Ionic or non-ionic detergents inactivate IFN-y, while as far as organic solvents are concerned only those with high polarity inhibit antiviral activity. Finally when different kinds of enzymes were used, proteases but not lipases or neuraminidase inactivated IFN-y.
