RESUMO
Purified beta-toxin from Clostridium perfringens type C was found to be a single polypeptide chain protein with a molecular weight of approximately 30,000. The toxin was heat labile, with 75% of its activity being inactivated by incubation at 50 degrees C for 5 min. Biological activity of the purified toxin was completely destroyed on exposure to trypsin for 30 min at 37 degrees C. The 50% lethal dose for mice was 1.87 microgram of purified toxin.
