ABSTRACT:
A method of recovering a purified and stabilized protein having antihemophilic factor activity (Factor VIII), from a biological sample containing Factor VIII, at least one destabilizing protease impurity, i.e. thrombin, and optionally one or more proprotease impurity, is provided. The biological sample is contacted with a protease removing and/or inhibiting agent, thereby inhibiting and/or removing the destabilizing protease impurity. The method provides increased yield and resolution of Factor VIII. Also provided are purified and stabilized Factor VIII non-lyophilized, liquid in compositions.
