Abstract
Carboxypeptidase B enzyme is isolated by a process wherein homogenized and autolyzed pancreas is subjected to a thermal treatment, and carboxypeptidase B is separated by fractionation with ammonium sulfate. This process produces carboxypeptidase B having satisfactory specific activity while eliminating the use of pancreas cell fluid or an acetonous powder from pancreas as a starting material. The isolated carboxypeptidase B may be immobilized on a polymer gel containing carboxy groups activated with a carbodiimide.
