Description
General Description
DSPE-mPEG is a versatile lipid-PEG conjugate designed for membrane anchoring and nanoparticle stabilization. The DSPE lipid anchor readily incorporates into liposomal membranes, lipid nanoparticles (LNPs), micelles, and other lipid-based delivery systems, while the hydrophilic mPEG chain extends into the aqueous environment, creating a protective steric barrier.
The mPEG segment reduces protein adsorption, minimizes opsonization, and improves colloidal stability, resulting in enhanced circulation time and improved in vivo performance. DSPE-mPEG is one of the most widely used PEGylated lipids for liposome engineering, lipid nanoparticle formulation, drug delivery systems, gene delivery platforms, and nanomedicine applications.
