title: Purification of pancreatic phospholipase A2 from human duodenal juice.
abstract: Phospholipase A2 (EC 3.1.1.4) was purified from delipidated human duodenal juice by hydrophobic and cation exchange chromatography, followed by molecular sieving on an HPLC column. The resulting enzyme preparation of phospholipase A2 had a molecular weight of 14 kDa, a specific activity of 2000 U/mg protein, and an N-terminal amino acid sequence which was characteristic for human pancreatic phospholipase A2.
