Abstract
A soluble ionic complex is formed by an aqueous mixture of a benzylammonium group-containing surfactant and a polynucleic acid sequence. When the mixture forms a vesicular complex, the sequence is packaged therein. This composition is useful in pharmaceutical compositions and in methods of delivering the polynucleic acid sequence (which preferably encodes a protein or peptide) to a cell for expression. Such methods are useful in therapy, as vaccines and as gene therapy agents.
