For the simple purification of porcine pancreas kallikrein, various affinity chromatographies using L-prolyl-L-phenylalanyl-L-arginine (Pro-Phe-Arg-OH), tosyl-L-arginine (Tos-Arg-OH) and acetyl-L-phenylalanyl-L-arginine (Ac-Phe-Arg-OH) as ligands were examined. The purification was performed as follows using the extract from acetone powder of porcine pancreas as starting
