Abstract

The present invention discloses a cationic lipid-based formulation for in vivo delivery of nucleic acid. The present invention describes the development of a lipid system that can induce efficient non-viral delivery of nucleic acid. especially RNA. for the purpose of efficient nucleic acid transfection toward eliciting vaccination in vivo. Present invention provides a lipid/RNA complex (lipoplex) formulation having sufficiently long shelf life that performs without any compromise in its transfection output. The present invention further provides cationic lipid-based formulations for RNA delivery with maximum nucleic acid complexation ability and with comparatively lesser amount of cationic lipid having higher stability.
