ABSTRACT:
The invention concerns a composition containing stabilised particles of cationic transfection agent(s)
ucleic acid complexes characterised 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.
