[Isolation of phospholipase A2 on biospecific supports]

The procedure of isolation of phospholipase A2 from Agkistrodon halys blomhoffii venom and porcine pancreas on biospecific supports of an organo-silica type with immobilized phospholipid is described. The purity of isolated enzymes was controlled by polyacrylamide gel electrophoresis, determination of the N-terminal amino acid and isoelectrofocusing. The enzyme activity was equal to 80 mumole/mg/min and 1400 mumole/mg/min for snake venom phospholipase and for pancreatic phospholipase A2, respectively.
