DSG-PEG (MW 2000) is a polyethylene glycol-conjugated lipid (PEG-lipid) primarily used as a key excipient in the preparation of lipid nanoparticles (LNPs) and liposomes. Its distearoyl glycerol anchor provides robust membrane anchoring within lipid bilayers. In nucleic acid delivery systems, DSG-PEG (MW 2000) modulates particle size, circulation stability, and cellular interaction kinetics, serving as a critical component for optimizing mRNA delivery efficiency and tissue targeting.
