    摘要: There is disclosed a method of producing a Factor VIII (AHF) containing fraction having a specific activity of at least 2.5 units of Factor VIII/mg protein as well as a portion of immunoglobulin G (IgG) of 10 mg/1000 units of Factor VIII at the most. Its risk of transmission of viral or bacterial infections is to be avoided or largely reduced. The method consists in that undesired proteins are at first precipitated from a Factor VIII (AHF) containing plasma fraction in the presence of SPS. The purified Factor VIII containing solution is treated with suitable salts or salt mixtures in order to obtain a Factor VIII containing precipitate. This precipitate is dissolved, lyophilized and finally heat-treated.

    摘要: In a method of producing a factor-VIII(AHF)-high-concentrate having a specific activity of at least 2.5 units AHF and a fibrinogen content of less than 0.25 mg/mg protein from human or animal plasma, the plasma is subjected to a multi-step fractionation. The fraction purified by these fractionation measures and enriched in factor VIII (AHF) is subjected to a cryoalcohol precipitation and the resulting precipitate is processed into a stable form.

    摘要: To produce lys-plasminogen having a specific activity of at least 17.5 caseinolytic units/mg protein and at least 50 mymoles/g protein nitrogen as well as an electrophoretic purity of at least 90%, plasminogen from plasma, a plasminogen-containing fraction or a tissue culture is adsorbed on immobilized lysine for the purpose of purification, is eluted and is recovered from the eluate by a protein precipitating agent. A solution of the thus purified plasminogen is adjusted to a plasmin activity ranging between 0.005 and 0.2 mymoles/ml min relative to chromogenic substrate H-D-valyl-L-leucyl-L-lysine-p-nitroanilide dihydrochloride, is maintained at a temperature of from +1.degree. C. to +20.degree. C. for a period of from 6 to 60 hours in order to provoke an enzymatic-proteolytic conversion of plasminogen into lys-plasminogen, whereupon the enzymatic action is interrupted and lys-plasminogen is isolated.
