DSPE-Carbamate-PEG-Maleimide, MW 2,000 constitutes a PEG lipid with DSPE attached to a 2k PEG polymer chain and a terminal maleimide, which will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. The PEG chain enhances the water-solubility of the molecule.
