DSPE-PEG2000-Maleimide (ammonium) is a PEGylated phospholipid composed of DSPE linked to a polyethylene glycol chain (average MW 2000) terminating in a maleimide group. The maleimide functionality enables selective conjugation to thiol-containing molecules, making this reagent useful for creating functionalized liposomes, nanostructured lipid carriers, and surface-modified nanoparticles. The PEG chain improves colloidal stability and extends circulation time.

  • Thiol-reactive maleimide end for selective covalent conjugation.
  • PEG2000 chain increases circulation time and colloidal stability.
  • Designed for liposome and nanoparticle surface functionalization.
  • Typically supplied as an ammonium salt white to off-white solid.
  • High purity suitable for research applications (manufacturer-specified).
