DSPE-PEG2000-Mal ammonium is a DSPE-PEG conjugate bearing a terminal maleimide group used to functionalize liposomes and lipid nanoparticles. The DSPE moiety anchors in lipid bilayers, PEG2000 provides steric stabilization and prolonged circulation, and the maleimide enables rapid, thiol-selective covalent attachment of ligands.

  • Enables thiol-selective covalent conjugation to biomolecules.
  • Anchors into lipid bilayers for stable surface presentation.
  • Provides PEGylation to extend circulation time and reduce opsonization.
  • Improves colloidal stability of liposomes and nanoparticles.
  • Suitable for targeted delivery and surface functionalization workflows.
