Lipid CP-LC-1428 is an ionizable cationic amino lipid derived from homocysteine, a naturally occurring amino acid. This lipid has demonstrated an efficient delivery and high protein expression of different kinds of RNA (mRNA, cRNA and saRNA) in vivo. Moreover, using a typical LNP formulation (IL/Ch/DOPE/PEG: 50/38.5/10/1.5), it has shown to induce specific spleen targeting much more efficiently that other commercial alternatives through IV injection, with no signs of toxicity.WARNING This product is not for human or veterinary use.
