DSPE-PEG-COOH (MW 2000) is a PEGylated phospholipid used to formulate liposomes and lipid nanoparticles for research applications. The DSPE moiety anchors in lipid bilayers while the PEG chain provides steric stabilization; the terminal carboxylic acid enables covalent conjugation to primary amines for surface functionalization.

  • Used to prepare liposomes and lipid nanoparticles for drug delivery research.
  • Terminal carboxylic acid enables amide bond formation with primary amines.
  • PEG2000 chain improves colloidal stability and circulation time.
  • White to off-white solid, suitable for storage and handling in laboratory settings.
  • Available in small pack sizes suitable for research-scale experiments.
