JenKem PEG RnDJenKem Technology’s monodisperse PEG products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. Monodisperse JenKem PEGs retain polyethylene glycol’s good solubility in water, offering to PEGylated drugs the same PEG benefits of reduced aggregation and immunogenicity, and increased hydrodynamic volume.

JenKem Technology’s monodisperse PEG products consist of linear chains of up to 48 –CH2-CH2-O– units, and various terminal functional and reactive groups. Monodisperse PEG products with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. GMP grade products and bulk products are available also by custom synthesis. Please inquire at tech@jenkemusa.com about pricing and availability.
