DSPE-PEG-Maleimide (MW 3400) ammonium is a phospholipid-PEG conjugate terminating in a maleimide reactive group (ammonium salt) used to functionalize lipid nanoparticle surfaces. It enables thiol-specific coupling of peptides, proteins, or small molecules to liposomes and nanostructured lipid carriers, providing steric stabilization and targeted-surface modification for drug delivery research.
- Functional maleimide group for thiol-specific conjugation.
- DSPE phospholipid anchor for stable insertion into lipid bilayers.
- PEG chain with nominal molecular weight 3,400 Da for steric stabilization.
- Ammonium salt form to aid solubility and handling.
- Intended for liposome and nanostructured lipid carrier preparation.
- Purity >95% (vendor specification).
- Polymeric PEG represented as (C2H4O)n; composition varies with chain length.
