Medchemexpress LLC DSPE-PEG-maleimide (MW 3400) ammonium | 474922-22-0 | >95.0% | 3,400 Da | (C2H4O)nC52H93N3NaO13P | 50 MG
Supplier: Medchemexpress LLC HYW441009A50MG
DSPE-PEG-maleimide (MW 3400) ammonium is a phospholipid-polyethylene glycol conjugate bearing a terminal maleimide reactive group. Supplied as the ammonium salt with a nominal PEG molecular weight of 3,400 Da, it is used to introduce thiol-reactive functionality into lipid assemblies for site-specific conjugation and formulation of PEGylated lipid nanoparticles and nanostructured lipid carriers.
- Provides maleimide functionality for thiol-specific conjugation.
- Anchors into lipid bilayers via DSPE for stable incorporation into liposomes and nanoparticles.
- PEG chain (3,400 Da) imparts steric stabilization and extended circulation.
- Compatible with thiol-containing ligands for targeted conjugation.
- Typically supplied at ≥95% purity; store under dry and low-temperature conditions.
