(FR) PARTICULES LIPIDIQUES CONTENANT DES ACIDES NUCLEIQUES ET PROCEDES ASSOCIES
Abstract
(EN) The present invention provides a method for preparing nucleic acid-lipid nanoparticles comprising the cationic lipid DLinKC2-DMA using a microfluidic mixing device, wherein the resulting nucleic acid-lipid nanoparticles exhibit smaller particle diameter and greater core density than nucleic acid-lipid nanoparticles of the same formulation produced b\ the conventional preformed vesicle method
(FR) La présente invention concerne une procédé pour préparer des nanoparticules d'acides nucléiques et de lipides, comprenant le lipide cationique DLinKC2-DMA, au moyen d'un dispositif de mélange microfluidique, les nanoparticules d'acides nucléiques et de lipides présentant un diamètre de particule plus faible et une densité de coeur plus élevée que les nanoparticules d'acides nucléiques et de lipides de la même formulation produites selon la méthode classique faisant intervenir des vésicules préformées.
