DMG-PEG2000-Biotin is a synthetic amphiphilic molecule composed of dimyristoyl glycerol (DMG), polyethylene glycol (PEG2000), and biotin functionalities. It is commonly employed in biomedical research for surface modification of lipid-based delivery platforms, such as lipid nanoparticles (LNPs) and liposomes. The PEG moiety enhances colloidal stability, prolongs circulation time, and reduces rapid clearance in vivo. The biotin termination facilitates conjugation to streptavidin-tagged biomolecules, exploiting the highly specific biotin-streptavidin interaction. Thus, DMG-PEG2000-Biotin is valuable for drug-delivery optimization, targeted therapeutic approaches, and in vitro diagnostic assay development.
