ABSTRACT:
A liposome composition for administration of a polynucleotide and a method of preparing the composition are described. The liposomes in the suspension are composed predominantly of liposomes having a bilayer membrane formed of cationic vesicle-forming lipids and neutral vesicle forming lipids. The polynucleotide is entrapped in the central core of the liposomes and is localized predominantly on the inner surface of the core.
