  • Patent number: 11066451
    Abstract: A method for purifying a clostridial neurotoxin comprising contacting a cation exchange resin with a composition comprising a clostridial neurotoxin, wherein the contacting step is performed at at least pH 7.3, wherein the step of contacting a cation exchange resin with a composition comprising said clostridial neurotoxin occurs prior to conversion of the clostridial neurotoxin from a single chain form into a dichain form. Also provided are uses of a buffer having a pH value that is ?1 pH unit or higher than the calculated pi of a clostridial neurotoxin, purification intermediates and clostridial neurotoxins obtainable by the invention, wherein the clostridial neurotoxin is in a single chain form.
