Abstract
Kallidinogenase (EC 3.4.4.21 substance) is extracted from the pancreas of a mammal with water at about 45-60 degrees C and pH 5-8 in the presence of a water-soluble salt of magnesium with an acid, pref. with a mineral acid or 1-5C fatty acid. The preferred concn. of the salt is 0.02-1 mole per litre of water. Pref. salts include MgCl2, MgSO4, Mg acetate and Mg propionate. The use of a magnesium salt, is opposed to the known use of alkali metal or ammonium salts, gives a prod. with superior heat stability, separability, turbidity and activity.
