BPG-1496 HS-PEG-Plys, PEG MW 1k-5k Inquiry

HS-PEG-Plys is a biodegradable polymer organic compound conjugated by polyethylene glycol and polylysine. It is a linear amphiphilic block copolymer with Plys as the hydrophobic part and PEG as the hydrophilic part. Plys part has side chain free amine group and has good membrane permeability. The PEG portion contains sulfhydryl groups. Plys can be used as a carrier for certain drugs, so it is widely used in medical and pharmaceutical applications. Various reactive groups in Plys-PEG derivatives can cross-link with different molecules. HS-PEG-Plys is readily oxidized by air to form S-S disulfide bonds, which can be reversed by reducing agents. It is a useful reagent for reversible PEG and PEG hydrogels.
