DSPE-PEG-Alkyne

Price range: $280.00 through $960.00

DSPE-PEG-Alkyne is an alkyne-functionalized lipid-PEG conjugate consisting of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE), polyethylene glycol (PEG), and a terminal alkyne group. The DSPE lipid anchor readily incorporates into liposomes and lipid nanoparticles, while the alkyne functionality enables efficient click chemistry conjugation with azide-containing molecules. DSPE-PEG-Alkyne is widely used in liposome engineering, lipid nanoparticle functionalization, targeted drug delivery, molecular imaging, and nanomedicine research.

Description

General Description

DSPE-PEG-Alkyne is a phospholipid–poly(ethylene glycol) conjugate containing DSPE (distearoyl phosphoethanolamine), a hydrophilic PEG spacer, and a terminal alkyne functional group. The alkyne group enables bioorthogonal click chemistry conjugation with azide-containing molecules.


Key Properties

  • Alkyne-functionalized lipid PEG conjugate
  • Suitable for click chemistry reactions (CuAAC / SPAAC-compatible systems)
  • DSPE lipid anchor for membrane incorporation
  • PEG spacer improves aqueous solubility and steric stabilization
  • Biocompatible lipid–polymer hybrid material

Applications

  • Liposome and lipid nanoparticle functionalization
  • Click chemistry bioconjugation
  • Surface modification of nanoparticles and biomaterials
  • Targeted drug delivery system development
  • Hydrogel and polymer conjugation
  • Diagnostic and imaging applications

Functional Overview

The DSPE lipid segment anchors into lipid bilayers, while PEG provides flexibility and stealth properties. The terminal alkyne group enables selective conjugation with azide-functionalized molecules through click chemistry reactions.


Summary

DSPE-PEG-Alkyne is a versatile click-functional lipid PEG conjugate widely used in lipid nanoparticle engineering, bioconjugation, and advanced drug delivery applications.
