[Isolation and purification of the active principle from agkistrodon acutus snake venom by high performance ion-exchange liquid chromatography].

The active component from Agkistrodon acutus snake venom was further purified by high performance ion-exchange liquid chromatography over a Protein-PAK DEAE-8HR column(10.0 mm i.d. x 100 mm). The elution was operated with a linear gradient from 10% to 100% NaCl-0.02 mol/L Tris-HCl buffer(pH 8.0). The quantitative results were calculated as 45.41% based on peak area nomalization and the purity of the active component was 90% determined by electrophoresis.
