Patent

CA 1337644

A method is provided for protecting a polymeric surface from degradation when subjected to ionizing radiation. The surface has a biologically active agent coupled thereto. The method involves applying a protective composition containing a surface- stabilizing agent and an oxygen-radical scavenger to preserve the activity of the biologically active agent coupled to the surface when the surface is subjected to sterilizing amounts of radiation. The surface- stabilizing agent is a high molecular weight agent such as is conventionally used in drying biologically active substances. The oxygen-radical scavenger is generally a polyol or a polyol moiety such as is provided by a saccharide. A polymeric surface prepared by the method of this invention and a method to conduct extra-corporeal treatment of body fluid is also provided.
