Moderna Lipid 26(Lipid M) is an ionizable cationic lipid (pKa = 6.75) that has been used in the generation of lipid nanoparticles (LNPs) for mRNA delivery in vivo. LNPs containing lipid M and encapsulating mRNA encoding influenza virus genes increase anti-influenza virus IgG titers in cynomolgus monkeys without inducing local edema, erythema, or systemic levels of IL-6.

Specifications shown are product-page values, not batch test results.
