Abstract
Two fragments with MW of 105,000 (fragment I) and 58,000 (fragment II) were separated chromatographically from each other after C. botulinum type A derivative toxin adsorbed onto a QAE-Sephadex column was treated with dithiothreitol and urea. They were antigenic and formed crossing precipitin lines against anti-derivative toxin in agar gel diffusion tests. Upon removal of dithiothreitol and urea by dialysis, the 2 fragments reassembled to reconstruct the derivative toxin molecule.This publication has 11 references indexed in Scilit:
