CONDITIONS OF STORAGE OF A PROTEIN COMPOSITION COMPRISING SURFACTANT AND DEVELOPMENT OF SURFACTANT CONTENT

摘要

The present invention relates to the use of a stopper coated with a film of tetrafluoroethylene polymer or copolymer for sealing a container containing a composition comprising at least one protein and at least one surfactant, characterized in that the polymer film or tetrafluoroethylene copolymer avoids or limits the decrease in the concentration of surfactant in said composition, or avoids or limits the adsorption of surfactant by said plug (2).
