DSPE-PEG-Maleimide (DSPE-PEG-MAL) is one of phospholipid PEG derivatives that composed of DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) and maleimide groups. DSPE-PEG-MAL is one of the most commonly used reactive phospholipids to conjugate antibodies, peptides or other ligands to the surface of liposome and other lipid PEG nanoparticles. Pegylated phospholipids have extended blood circulation time and higher stability for encapsulated drugs.

It is often used in targeted drug delivery with the lipid bilayer to improve drug solubility, the PEG to provide stealth property, extend circulation half-life and reduce non-specific protein binding or cell adhesion, and the reactive maleimide to bioconjugate targeting molecules including antibody, aptamer, protein, and peptide.

Biopharma PEG provides high purity DSPE-PEG-MAL with various molecular weights and excellent chemical reactivity. These lipid PEG conjugates demonstrate excellent amphilphilic properties and offer superior advantages for small and large molecule drug formulation and delivery.
