JenKem Technology’s monodisperse PEG products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. JenKem monodisperse discrete PEGs retain the 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 catalog monodisperse PEG products consist of linear chains of five to twelve –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. Please inquire at firstname.lastname@example.org about pricing and availability of custom monodisperse PEGs. Bulk PEGs and GMP PEGs are also available upon request. Please contact us for special bulk pricing.
