JenKemBeijingRnDJenKem Technology provides high quality activated homobifunctional polyethylene glycol derivatives (PEGs) with high purity and low polydispersity.

JenKem Technology’s homobifunctional PEG derivatives have numerous applications as cross-linkers, including PEGylation of proteins and peptides, or nanoparticle and surface modifications [1, 2]. Homobifunctional PEG derivatives have the general structure: X―PEG―X, where X is a functional reactive group.

Homobifunctional PEG products with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at tech@jenkemusa.com about pricing and availability of custom homofunctional PEGs.

JenKem Technology provides GMP grade PEG derivatives and bulk orders via custom synthesis, offering the opportunity to match customers’ special quality requirements. JenKem Technology is capable of development and synthesis of a wide range of GMP PEG derivatives starting at 200g up to 40 kg or greater batches, under ISO 9001 and ISO 13485 certified quality management system, following ICH Q7A guidelines.
