Title
(EN) LIPID-NUCLEIC ACID PARTICLES PREPARED VIA A HYDROPHOBIC LIPID-NUCLEIC ACID COMPLEX INTERMEDIATE AND USE FOR GENE TRANSFER
(FR) PARTICULES D'ACIDES NUCLEIQUES ET DE LIPIDES PREPAREES AU MOYEN D'UN INTERMEDIAIRE DE COMPLEXE HYDROPHOBE D'ACIDES NUCLEIQUES ET DE LIPIDES ET UTILISATION POUR TRANSFERER DES GENES
Abstract
(EN)
Novel lipid-nucleic acid particulate complexes which are useful for in vitro or in vivo gene transfer are described. The particles can be formed using either detergent dialysis methods or methods which utilize organic solvents. Upon removal of a solubilizing component (i.e, detergent or an organic solvent) the lipid-nucleic acid complexes form particles wherein the nucleic acid is serum-stable and is protected from degradation. The particles thus formed have access to extravascular sites and target cell populations and are suitable for the therapeutic delivery of nucleic acids.
