title: A new purification procedure for Clostridium difficile enterotoxin.
abstract: Clostridium difficile produces two toxins, an enterotoxin and a cytotoxin. The enterotoxin was purified using fast methods (tangential flow filtration, fast protein liquid chromatography). The purified enterotoxin is composed of two subunits (A1 = 41,500, A2 = 16,000) and its pI is 3.5.
