Capabilities

Controlled manufacturing of polyethylene glycol (PEG) polymers with targeted molecular weights and functionality via the polymerization of ethylene oxide in 5kg, 15kg, 20kg, and 100kg batches, as needed, with annual capacity of over 10 metric tons of high quality raw PEGs and m-PEGs, with a new plant that has come on stream in 2017 which also has the capability of the purification of these raw PEGs under GMP conditions if needed for even higher quality products.

Development and manufacture of a wide range of PEG derivatives with high purity and low polydispersity, currently in 1 gram to 40 kg or greater sized batches, under ISO 9001 and ISO 13485 certified Quality Management Systems, following ICH Q7A guidelines and operating under cGMP protocols for regulated customers.

Custom synthesis of Y-Shaped PEGs, Methoxy PEGs, Homobifunctional PEGs, Heterobifunctional PEGs, Multi-arm PEGs, Multi-arm Heterobifunctional PEGs, Monodisperse (Discrete) PEGs, Biodegradable PEG Co-Polymers (such as PEG-PLGA, PEG-PLA, PEG-PCL, and other block polymers), and PEG GPC Standards.

Custom PEGylation of proteins, peptides, oligonucleotides, and small molecules; and conjugation of PEGs to other polymer systems. Large scale manufacturing on a custom synthesis basis, which offers the flexibility to match a customer’s specifications.

Global distribution of JenKem® PEG products direct from China and many research grade PEG derivatives sold through a collaboration with MilliporeSigma, link., listed in their catalog and on their website and identified as being a product of JenKem Technology.
