DSG-PEG-NH-Mal, MW 2,000 is a PEG lipid polymer used in the formulation of liposomes and lipid nanoparticles (LNPs). It incorporates into lipid bilayers and contributes to colloidal stability and extended circulation time. The terminal maleimide reacts with cysteine-bearing biomolecules to form thiol linkages. The 2k polyPEG greatly enhances aqueous solubility. Reagent grade, for research use only.
