DSPE-PEG-IA (MW 3400)

DSPE-PEG-IA, MW 3400, is an iodoacetyl-based PEG lipid. This polymer spontaneously forms lipid bilayers or micelles in aqueous solutions. The lipophilic tail can encapsulate hydrophobic therapeutic agents, while the hydrophilic head can encapsulate hydrophilic drugs/nutrients, including antibodies and mRNA/DNA. The iodoacetyl group reacts with thiols to form thioether bonds. Reagent grade, for research use only.
