With it's state-of-the-art screening tools, Immorna has developed an arsenal of mRNA delivery vehicles including polymeric, lipid nanoparticles and other novel nano-carriers featuring multiple proprietary ionizable or cationic moieties suitable for intramuscular, intravenous, and tissue-targeting delivery. These nano-carriers encapsulate and carry the mRNA cargo to its targeted cells. Followed by endocytosis/endosomal escape or direct fusion, the mRNA payload is released into cytoplasm.
