m-dPEG®25-DSPE, product number QBD-11373, modifies the lipid 1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) with a long (77 atoms, 90.0 Å), methoxy-terminated, single molecular weight, discrete polyethylene glycol (dPEG®) spacer. This product is designed to protect liposomes and micelles from opsonization and elimination by the reticuloendothelial system (RES). The m-dPEG®25 spacer offers protection from opsonization comparable to the traditional polymer mPEG2000, while the smaller spacer size compared to mPEG2000 allows for more efficient uptake into cells. The methyl-capped dPEG® spacer has a neutral charge.
Vector Laboratories’ dPEG® products are highly pure single molecular weight compounds with a discrete chain length. Traditional PEG compounds used to coat liposomes and micelles consist of an intractable mixture of different chain lengths and molecular weights. The non-uniform polymeric mixture leads to irreproducible purity profiles, unlike dPEG® compounds.
