Stable composition of gamma-interferon.

摘要

The present invention relates to a human gamma -interferon composition frozen or lyophilized in the substantial absence of inorganic salt and in the presence of amino acid. The activity of the above composition decreases very little during freezing or lyophilization and during storage. Upon thawing or reconstitution of the composition, no turbidity is produced. Therefore, the composition can advantageously be used as an antiviral or antitumor agent, among others.
