CONSTITUTION: A purification method of Clostridium botulinum type A toxin comprises the steps of: (a) adding sulphuric acid into a Clostridium botulinum type A strain cultured medium up to pH 3 to 4 to produce and obtain a precipitate; (b) dissolving the precipitate in a buffer solution and adding ammonium sulfate into the buffer solution to obtain a precipitate; (c) diluting the precipitate in a phosphate buffer solution, treating the diluted solution with RNA hydrolyase and adding ammonium sulfate into the supernatant to obtain a precipitate; (d) dissolving the precipitate in a buffer solution and subjecting the buffer solution to ion exchange chromatography to obtain a fraction having A260/280 value of 0.6 or more; and (e) subjecting the fraction to gel filtration chromatography.
