18:1 PEG2000 PE ammonium salt is a PEGylated phosphoethanolamine that attaches a methoxy-PEG2000 chain to phosphatidylethanolamine, enabling incorporation of a hydrophilic PEG surface into lipid bilayers and nanoparticle formulations. It is used in liposome and nanoparticle preparation, membrane model studies, and surface modification to impart steric stabilization and reduce aggregation.
- Provides steric stabilization to lipid bilayers and nanoparticles.
- Increases hydrophilicity and reduces aggregation of lipid assemblies.
- Suitable for liposome and nanoparticle formulation and membrane model systems.
- Reported high purity (>99%), suitable for research applications.
- Powder form; hygroscopic and recommended storage at -20 °C.
