Heterobifunctional Linear PEGs

Heterofunctional PEG derivatives are often used as crosslinkers or spacers between two different chemical entities.

Its general structure is: X-PEG-Y, where X and Y are two different functional groups or reactive groups. We offer many combinations of X and Y such as acetal, acid, acrylamide, acrylate, aldehyde, alkyne, amine, aminooxy, azide, biotin, boc-protected amine, coonhs, cootbu, dibenzocycolctyne (dbco), dioxoisoindolin, epoxy, fmoc -protected amine, folate, folic acid, hydrazide, hydroxy, hydroxyi, isocyanato, lipoic acid, maleimide, methacrylate, methoxy, nhs, orthopyridyi disulfide (opss), pentafluorophenyl (pfp) ester, silane, tetrafluorophenyl (tfp) ester, thilo, thiol, and vinyl sulfone/nhs.

Heterofunctional PEG derivatives are particularly useful in the development of antibody drug conjugates (ADCs), and ADCs conjugated with heterobifunctional PEGs exhibit improved water solubility and PK/PD profiles.
