DSPE-PEG-carbonate ester, MW 2,000 serves as a PEG lipid comprised of NHS carbonate ester, which labels the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules, and DSPE, which allows for self-assembly in water to form a lipid bilayer and preparation of liposomes as drug nanocarriers. The 2k polyPEG units bolster water-solubility of the molecule. Reagent grade, for research purpose.
