Compositions and methods for mediating RNAi in vivo

摘要

This invention relates to new formulated lipid particles (FLiPs) comprising at least one of a single or double stranded oligonucleotide, where the oligonucleotide has been conjugated to a lipophile and at least one of an emulsion or liposome to which the conjugated oligonucleotide has been aggregated, admixed or associated. These particles have surprisingly been shown to effectively deliver oligonucleotides to heart, lung and muscle where they effect gene silencing.
