Maleimide PEG Hydroxyl


PEG products with additional MW may be made to order, please contact us for details


High quality Maleimide PEG Hydroxyl with standard quality specification of ≥95% Substitution.

Heterobifunctional Maleimide PEG Hydroxyl products from JenKem Technology are generally employed as crosslinking agents or as spacers between two different chemical entities. The PEG moiety in the heterofunctional PEG derivatives provides water solubility, biocompatibility, and flexibility. Applications are especially geared towards the development of antibody drug conjugates (ADC’s).

Heterobifunctional PEGylation reagents with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at about pricing and availability of custom PEGs.

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