Abstract

The present invention relates to liquid formulations of human interferon-β. The formulations are characterized in that they have a buffer with a pH in the weakly acidic to neutral range of between 5 and 8, preferably between over 5.5 and 8, and that they exhibit high stability of the interferon-β in solution while retaining the molecular integrity.
