DSPE-PEG-NH2 (DSPE-PEG-Amine), MW 5K is a linear heterobifunctional PEGylation reagent. Can be used to prepare grafted or PEGylated liposomes or micelles, while also providing amine groups for bioconjugation. Because of its properties that increase drug solubility, prolong circulatory half-life and reduce nonspecific protein binding or cell adhesion, it is often used for targeted drug delivery.
