    Product Description

    DSPE-Polysarcosine150 is an amine-functionalized, hydrophilic polymer.1 It is a polysarcosine-labeled form of 1,2-distearoyl-rac-glycero-3-PE (DSPE). Polysarcosines have been used as alternatives to PEGylation in lipid nanoparticles (LNPs) and to reduce the immunogenicity of administered proteins in vivo.1,2

    WARNING This product is not for human or veterinary use.
