  • Method of preparing a topical fibrinogen complex
    Patent number: 5792835
    Abstract: A method for preparing a fibrinogen-containing composition derived from human plasma by separating a cryoprecipitate from the plasma, suspending the cryoprecipitate in a salt-containing buffer, treating the supernatant by affinity-chromatography on a lysine-bound solid matrix to allow plasminogen to adsorb thereon, collecting a fraction containing less than 10 .mu.g/ml plasminogen, and treating the fraction to reduce viral activity. The fibrinogen-containing composition recovered from this fraction is advantageous because it contains such a low amount of plasminogen that no addition of fibrinolysis inhibitor is needed.

  • Ultrapurification process for factor VIII
    Patent number: 5470954
    Abstract: A process for purifying Factor VIII:C comprising contacting an immobilized antibody specifically binding a Factor VIII:C with Factor VIII: C, desorbing Factor VIII:C from the antibody which had adsorbed it, eluting Factor VIII:C from the presence of the antibody, passing the eluted Factor VIII:C through an affinity region capable of binding the Factor VIII:C, binding the Factor VIII:C in the affinity region and passing contaminants through said region, and eluting the purified Factor VIII:C.
