A drug-carrier matrix has been developed which protects embedded insulin from degradation by the luminally secreted serine-proteases trypsin (EC 3.4.21.4), chymotrypsin (EC 3.4.21.1) and elastase (EC 3.4.21.36) in vitro. Increasing amounts of the Bowman-Birk inhibitor (BBI) and elastatinal, respectively, were

Human leukocyte elastase can be proteolytically inactivated by bovine pancreatic trypsin. Neither porcine pancreatic elastase nor bovine pancreatic chymotrypsin causes inactivation of leukocyte elastase, nor are trypsin, pancreatic elastase, or chymotrypsin themselves susceptible to proteolysis. The trypsin-catalyzed inactivation of leukocyte
