ABSTRACT:
The present invention relates to a composition and method that optimizes retention of physiological activity of a biologically active compound during sterilization of said compound with gamma or electron-beam radiation. The method comprises the steps of forming a protected mixture that comprises the biologically active compound, an extraneous protein, and a free-radical scavenger, and irradiating the protected mixture with about 1 to about 3 mRad of gamma or electron-beam radiation.
