| 摘要 |
A plasminogen preparation contains at least one of a physiologically acceptable inorganic salt, lysine, a salt thereof, phenylmethanesulfonyl fluoride, aprotinin, or soybean trypsin inhibitor in an amount effective for stabilizing plasminogen. The preparation may take the form of an aqueous solution or a dry powder. The preparation can be prepared by adding the abovementioned stabilizer or stabilizers to an aqueous solution containing plasminogen, if necessary subjecting the resulting solution to digestion at 4 DEG to 37 DEG C at pH 2 to 4 for 20 to 60 minutes, and then to heat-treatment at 60 DEG C for 10 hours, and lyophilizing the resulting solution. |
