SERINE-PROTEASE INHIBITION DURING ISLET ISOLATION INCREASES ISLET YIELD FROM HUMAN PANCREASES WITH PROLONGED ISCHEMIA1
Background. Islet isolation from the pancreatic tissue matrix remains highly variable. Recent
evidence suggests that intrinsic human pancreatic proteases, including trypsin, may inhibit …
