SUNBRIGHT DSPE-050MA is a functionalized PEG phospholipid designed to enhance the performance of lipid nanoparticle (LNP) and liposomal formulations in active targeting delivery systems. It features a maleimide group linked to the PEG chain of DSPE-PEG5000, providing a versatile platform for bioconjugation. The maleimide group enables site-specific conjugation with thiol-containing molecules (such as peptides, antibodies, or other ligands), facilitating efficient ligand conjugation and resulting in precise cellular targeting and enhanced formulation versatility.
