Abstract

Tonin has been purified from rat submaxillary glands. The purification procedure included affinity chromatography on Sepharose 4B coupled to antitonin followed by DEAE chromatography and gel filtration on Sephadex G-100. Homogeneity of the purified enzyme was confirmed by Sephadex G-100 gel filtration, disc electrophoresis, and isoelectric focusing on polyacrylamide gel, immunodiffusion, and immunoelectrophoresis. The tonin was purified 11.5-fold, with 35% recovery. The purified tonin has full enzymatic or immunological activity.
