title: Purification of Pseudomonas aeruginosa exotoxin by affinity chromatography.
abstract: Pseudomonas aeruginosa exotoxin A was purified by affinity chromatography from culture supernatants by elution of toxin from antitoxin immunoglobulin G-Sepharose 4B with 3 M NaSCN. The purity, toxicity, and enzymatic activity of exotoxin obtained were comparable to those of toxin purified by previously reported multiple-step procedures.
