EN Lipid Nano Particle for mRNA & RNA therapeutics

Lipid Nanoparticles (LNPs) are the most clinically advanced non-viral gene delivery system. It safely and effectively delivers nucleic acids, overcoming a major barrier preventing the development and use of genetic medicines.

Lipid nanoparticles offer many advantages over previous lipid-based nucleic acid delivery systems including:
  • High nucleic acid encapsulation efficiency and potent transfection
  • Improved penetration into tissues to deliver therapeutics
  • Low cytotoxicity and immunogenicity
