Abstract
There is provided, in accordance with practice of this invention, a process for separating Factor IX and/or Factor X from an impure protein fraction containing protein in addition to Factors IX and X. A silica resin coupled with a ligand capable of binding Factor IX and/or Factor X is provided. An aqueous solution of the impure protein fraction is applied to the ligand-coupled silica resin to thereby bind the Factor IX and/or Factor X to the resin. The Factor IX and/or Factor X is then recovered from the resin by elution.
