Formulation of stabilized cationic transfection agent(s) /nucleic acid particles

摘要

The invention concerns a composition containing stabilized particles of cationic transfection agents/nucleic acid complexes characterized in that it includes besides said transfection agent and nucleic acid at least a non-ionic surfactant in sufficient amount for preventing the aggregation of the particles in course of time. In a preferred embodiment, the surfactant is a polyoxyalkylene or a derivative thereof.
