TCL053, an ionizable lipid carrier, efficiently facilitates the introduction of active components, particularly nucleic acids, into cells. In combination with Dipalmitoylphosphatidylcholine (DPPC), Polyethylene glycol dimyristoyl glycerol (PEG-DMG), and cholesterol, TCL053 composes a lipid nanoparticle (LNP) system capable of delivering Cas9 mRNA and sgRNA into skeletal muscle [1] [2].
