Lipids & Polymers

DSPE-PEG-OH, MW 2,000 is a polyPEG containing a DSPE phospholipid and a hydroxyl group. 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 polyPEG chain increases the water solubility of the overall compound allowing for the delivery of the drug. The hydroxyl group allows for further derivatization of the compound. Reagent grade, for research purpose.
