A novel method for the isolation of carboxypeptidase B

Carboxypeptidase B was isolated from porcine pancreas by selective heat treatment of the autolyzed tissue at 60 degrees C and pH 6.0 the presence of phosphate ions. The heat treatment was followed by ammonium sulfate fractionation and ion-exchange in a batch system. The method could also be used for the isolation of carboxypeptidase B from beef pancreas.
