Zusammenfassung:A method for purifying antithrombin-III from an antithrombin-III-containing aqueous solution, comprising at least one of the following steps (a) and (b): (a) heating the antithrombin-III-containing aqueous solution in the presence of a stabilizing agent so that 85% or more of the activity of antithrombin-III before the heating is maintained after the heating, and that the ratio of an antithrombin-III monomer after the heating is maintained at 95% or more; and (b) treating the antithrombin-III-containing aqueous solution with a metal chelate resin and recovering a purified antithrombin-III.
