Polyethyleneglycols (PEG) (for DDS)

Polyethyleneglycols (PEG) (for DDS) — contains polyethylene glycol (PEG) and its methyl ether derivatives with molecular weights ranging from hundreds to tens of thousands of daltons, from PEG 1000 to PEG methyl ether 20000. This group of synthetic polymers is widely applied in drug delivery system (DDS) engineering because of its hydrophilic and biocompatible properties.

PEG and its derivatives are used by DDS formulation researchers to modify the surfaces of nanoparticles, liposomes, or proteins through PEGylation, in order to extend circulation time and alter solubility properties. Variation in molecular weight, from PEG 1000 to PEG methyl ether 20000, allows the polymer chain size to be adjusted to conjugation needs in materials research and functional polymer research.

Example products in this collection: TCI P3095 9004-74-4 Polyethylene Glycol Monomethyl Ether 220, TCI H0543 25322-68-3 Polyethylene Glycol 300, TCI P3061 Polyethylene Glycol Methyl Ether 20000, TCI N0443 25322-68-3 Polyethylene Glycol 400, TCI P3060 Polyethylene Glycol Methyl Ether 10000, TCI P0840 25322-68-3 Polyethylene Glycol 200, TCI P2830 25322-68-3 Polyethylene Glycol 20000, TCI P0885 25322-68-3 Polyethylene Glycol 4000.

The main selection is based on the average molecular weight and the type of end group (free hydroxyl on standard PEG or methyl ether on PEG monomethyl ether), because both determine the reactivity of the end group for further conjugation. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
