Abstract

An improved process for purifying proteins, particularly proteins having molecular weights in excess of 12,000 involves novel applications of high performance liquid chromatography on a preparative scale to provide homogeneous end product in excellent yield. In an embodiment of the process, human interferon is produced as a homogeneous protein.
