DSPE-PEG-NHS ester, MW 2,000

DSPE-PEG-NHS ester, MW 2,000 serves as a polyPEG lipid with DSPE and a terminal NHS ester which directly and efficiently reacts with amine-containing molecules. The DSPE-PEGs have been FDA-approved for medical applications. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic 2k polyPEG increases the overall water solubility of the compound, allowing for the delivery of the drug.
