AboutJenKemTianjin

Founded in 2001 by experts in PEG synthesis and PEGylation, JenKem Technology specializes in high-purity, low polydispersity polyethylene glycol (PEG) derivatives, PEG co-polymers, monodisperse PEGs, custom PEG derivative synthesis and PEGylation services. Specific strengths are supported by access to bulk ethylene oxide and the performance of all polymerizations and derivatizations in-house.

JenKem Technology supplies PEG derivatives worldwide, from R&D through GMP commercial quantities, for preclinical, clinical trials, and commercial products for pharma, biotech, medical devices, and diagnostics.

Capabilities

Development and manufacture of a wide range of PEG and PEG co-polymer 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. Capable of operating under cGMP protocols for regulated customers.

Controlled manufacture of raw polyethylene glycol 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, 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.

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

Custom PEGylation of proteins, peptides, oligonucleotides, and small molecules; and conjugation of PEGs to other polymer systems.

Online ordering of  JenKem® catalog PEG products available on our website, with global distribution of JenKem® PEG products direct from JenKem Technology China facilities. Many research grade PEG derivatives sold through a collaboration with MilliporeSigma, listed in their catalog and on their website and identified as being a product of JenKem Technology. Large scale and GMP manufacturing offered on a custom synthesis basis, with flexibility to match customers’ specifications.
