Chromatographic purification of at least one enzyme selected from a group including collagenase type i, collagenase type ii, neutral protease and clostripain

Abstract

The present invention relates to a method for purifying at least one enzyme selected from the group consisting of collagenase type I, collagenase type II, neutral protease and clostripain from a mixture of substances, comprising as a method step at least one hydrophobic interaction chromatography, characterized in that, in the hydrophobic interaction chromatography, the stationary phase comprises a material selected from the group consisting of polypropylene glycol and butyl sepharose. The present invention further relates to the use of an enzyme thus purified for pharmaceutical, cosmetic and/or biochemical purposes.
