title: Purification and some properties of a low molecular weight trypsin inhibitor from acute pancreatitis urine.
abstract: Urinary trypsin inhibitors (UTIs) from the urine of a patient with acute pancreatitis consisted of three forms with different molecular weights. These were highly purified by ammonium sulfate precipitation, Sephadex G-75, SP-Sephadex C-25 and trypsin-Sepharose 4B column chromatography. The lowest molecular weight of UTIs was estimated to be 6,200 daltons. Moreover, five residues of N-terminal amino acids and a C-terminal amino acid were the same as those of pancreatic secretory trypsin inhibitor.
