DSPE-PEG-Amine ammonium salt, MW 2,000 is a PEG polymer containing DSPE and a terminal amine. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG bolsters the water solubility of the molecule, allowing for the delivery of the drug. The amine group can react with activated NHS ester to form a stable amide bond.
