Elastase is prepared from porcine pancreas. It is lyophilised and water soluble. Elastase is chromatographically prepared by the method of Narayanan and Anwar. In the method, 2 times crystalline elastase is adsorbed on a column of DEAE-Sephadex A50 to separate elastase and non-specific protein components. The elastase component is further purified by chromatography on a column of CM-Cellulose using a sodium chloride gradient to elute the elastase. The latter is dialysed until chloride-free and then lyophilised. During its preparation the elastase is held below a pH of 5,5 for greater than 24 hours. Two times crystallised from the euglobin fraction of porcine pancreas by the method of Lewis et al. Does not contain trypsin or chymotrypsin.
