Abstract
This invention relates to a method for producing a plasminogen preparation which has been pasteurized to produce a hepatitis safe injectable plasminogen. The method comprises: adding to an aqueous solution of plasminogen the protective agent of methyl lysine ester, or ethyl lysine ester or a hydrochloride salt thereof which has antifibrinolytic acitivity to thereby attach the agent to plasminogen and form a modified plasminogen; and subjecting the resulting modified agent to a heat treatment of at least 60.degree. C. for at least 10 hours. Further, the protective agent may be separated from the modified plasminogen by affinity chromatography.
