摘要: Toxin derivatives are prepared by proteolytic treatment of holotoxin, and their toxicity is reduced by contacting the preparation with a ligand, which can be a metal or an antibody or another ligand. This ligand selectively binds to the toxin but not to the toxin derivative. Removing the ligand and toxin bound to the ligand further reduces toxicity. A second ligand is used to remove conjugates of the toxin and the first ligand. Compositions contain the purified derivative, optionally plus the toxin and the ligand.
