Activated PEGs for Thiol PEGylation

JenKem Technology manufactures high quality activated PEG products for thiol PEGylation, or sulfhydryl PEGylation. Methoxy PEG Maleimide is selective for thiol groups on cystein side chains of proteins. The sterically bulky Y-shape PEG Maleimide facilitate the single point attachment to thiol containing molecules.Methoxy PEG Vinylsulfone is a sulfhydryl reactive PEG that reacts at high pH. Methoxy PEG Thiol (polydisperse and monodisperse) are thiol reactive towards HS groups on cysteine side chains under mild reaction conditions.

Activated PEG products for thiol PEGylation with molecular weights, branching, 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 PEGs for thiol PEGylation.

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.
