The invention relates to a process for the preparation of the highly pure enzyme kallikrein from organ extracts, in particular from swine pancreas extracts, the accompanying proteolytic activity of the swine pancreas extract being separated off by chromatography on ion exchangers and the highly pure enzyme kallikrein being obtained by chromatography on support materials with a kallikrein-trypsin inhibitor (basic pancreatic trypsin inhibitor=BPTI) covalently bonded in a particular manner.
