摘要

Plasma Protein Fraction substantially free of bradykinin, kininogen and prekallikrein activators is obtained by treating Cohn Supernatant II plus III at about neutrality with a siliceous substance for a period of time sufficient to bring about essentially complete conversion of intrinsic kininogen into bradykinin. Subsequently, after being separated from Cohn Fraction IV-1, the Plasma Protein Fraction is reconstituted and held for a period of time sufficient to allow substantially complete destruction of bradykinin by kininase. Methods are disclosed for the destruction of prekallikrein activators which may be present in Plasma Protein Fraction.
