DSPE-PEG-SH (average MW 1,000 Da) is a thiol-terminated PEGylated phospholipid combining a DSPE lipid anchor with a polyethylene glycol spacer that ends in a reactive sulfhydryl. Supplied as a solid, it is used to introduce surface-accessible thiol groups into liposomes, lipid nanoparticles, and other lipid assemblies for bioconjugation and targeted delivery applications.
- Provides a lipid anchor for stable incorporation into bilayers.
- Contains a terminal thiol (-SH) for conjugation to thiol-reactive reagents.
- Average molecular weight ~1,000 Da for the PEG spacer.
- Facilitates surface functionalization of nanoparticles and liposomes.
- Typically supplied as a powder with high purity (≥95%).
- Useful for preparing targeted delivery systems and bioconjugates.
