Methyltetrazine-PEG3-Amido-PEG4-Mal-3,4-Dibromo is a unique PEG linker containing a TCO-reactive methyltetrazine group and a dibromomaleimide group which allows for two points of attachment because both of the bromine atoms can be substituted. The PEG spacer enhances the solubility of the molecule in aqueous solution.
