  • Method for purification of antithrombin III using an anion exchanger
    Patent number: 6395880
    Abstract: A method of purifying antithrombin III (AT III) from a starting material containing an AT III/heparin complex or an AT III/heparinoid complex is disclosed. First, the method comprises adsorbing the AT III/heparin complex or the AT III/heparinoid complex on an anion exchanger material. Second, the method involves separating the AT III from the adsorbed AT III/heparin complex or an AT III/heparinoid complex by elution with a buffer having a pH ranging from 8.5 to 10.5 and a conductivity between 10 and 60 mS.
