High quality OPSS PEG Succinimidyl Carboxymethyl Ester with a standard quality specification of >90% Substitution.
Heterobifunctional OPSS PEG Succinimidyl Carboxymethyl Ester 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. The thiol reactive OPSS group offers the ability to form a disulfide bond, while the SCM group reacts with the amine group of lysine(s). 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 email@example.com about pricing and availability of custom PEGs.
Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
