Description

Superior quality PEG Dithiol (PEG (Thiol)2; (diThiol PEG)) from JenKem Technology (≥ 95% purity) is a homobifunctional thiol reactive PEG derivative selective for sulfhydryl groups on cystein side chains under mild reaction conditions. Homobifunctional PEG derivatives from JenKem Technology have numerous applications as crosslinkers for PEGylation of proteins and peptides, nanoparticle and surface modifications. Conjugation with homobifunctional PEGs ensures an increased drug load compared to pegylation with linear PEGs. JenKem Technology offers Thiol PEG Thiol with MW 3,500 Da (HS-PEG3500-SH) and MW 5,000 Da (HS-PEG5000-SH), in 1g and 5g packing sizes.

Different MW of PEG (Thiol)2 may be available by custom synthesis, please email us at tech@jenkemusa.com for details on custom PEGs. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection.

Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
