title: A conjugate of trypsin and chymotrypsin.
abstract: A heteroenzyme conjugate retaining activities of two component enzymes from trypsin and chymotrypsin was prepared using N-succinimidyl pyridyl dithiopropionate as crosslinking reagent. The conjugate bound to both trypsin and chymotrypsin affinity columns. Trypsin and chymotrypsin were linked in the ratio of 1:1 on mol basis. The conjugate, when treated with dimethyladipimidate, showed decreased autolysis of its trypsin component.
