Abstract

Se describe un método para purificar una neurotoxina clostridial que comprende poner en contacto una resina de intercambio catiónico con una composición que comprende una neurotoxina clostridial, donde la etapa de contacto se realiza al menos pH 7.3, donde se produce la etapa de poner en contacto una resina de intercambio catiónico con una composición que comprende la neurotoxina clostridial antes de la conversión de la neurotoxina clostridial de una forma monocatenaria en una forma bicatenaria. También se proporcionan usos de una solución amortiguadora que tiene un valor de pH que es -1 unidad de pH o superior al pI calculado de una neurotoxina clostridial, intermediarios de purificación y neurotoxinas clostridiales obtenibles por la invención, en donde la neurotoxina clostridial está en una forma monocatenaria.
