DSG-PEG-NH₂, MW 2K is an amphiphilic PEG-lipid conjugate consisting of a hydrophobic DSG segment, a 2000 Da PEG spacer, and a reactive primary amine group. It is commonly used for bioconjugation with activated esters or carboxyl groups, and for surface functionalization of liposomes and lipid nanoparticles to improve stability and enable targeted drug delivery.
