  • Compositions containing at least one nucleic acid
    Patent number: 6387396
    Abstract: A composition containing a plurality of multicellular vesicles and at least one nucleic acid, at least one part of which is found included inside the multilamellar vesicles. Each of the vesicles is formed of a succession of lamellar bi-layers extending from each vesicle center to its periphery and including at least one surfactant agent. The bi-layers are concentric and are separated by a liquid medium. Such compositions can be used in pharmaceutics, particularly gene therapy, and in in vitro and in vivo transfection.

  • COMPOSITIONS CONTAINING AT LEAST ONE NUCLEIC ACID
    Publication number: 20020012696
    Abstract: The invention concerns a composition containing at least one nucleic acid a part of which at least is enclosed in multilamellar vesicles, characterised in that said vesicles consist of two layers comprising at least one surfactant, the said two layers being concentric and giving said vesicles an onion-like structure. The surfactants used are non-cationic surfactants. The invention concerns the use of such compositions in pharmaceutics, particularly in gene therapy and in in vitro and in vivo transfection.
