Isolation of cathepsins D by affinity chromatography]

The paper deals with the isolation of cathepsin D from rat liver, chicken liver and bovine spleen by affinity chromatography. The synthesis of the adsorbent was performed using the competitive inhibitor of cathepsins D and pepsin pepstatin and activated Sepharose. Application of a pepstatin-Sepharose column allows obtaining a highly active and purified enzyme in a short period of time.
