Abstract (en)
A blood coagulation Factor IX preparation is separated from plasma by selective adsorption of Factors II, IX and X, to the substantial exclusion of Factors VII and VIII, with 0.025-0,1% by weight of a water-insoluble, crosslinked polyelectrolyte copolymer of ethylene and maleic anhydride containing pendant diloweralkylaminoloweralkyl functional groups.
