Methyltetrazine-PEG3-maleimide linker has a table methyltetrazine on one end and a maleimide on the other. The methyltetrazine is ideal TCO biorthogonal for conjugations. The maleimide moiety can extensively used in ADCs for conjugation with free thiol group of the biomolecules.
The PEG spacer increases the solubility, minimizes the immunogenicity and improves pharmacokinetics of ADCs. The short PEG chain has shown to reduce aggregation of ADCs and prevent fluorophore quenching.
