Sulfo DBCO-PEG8-Maleimide serves as a bifunctional PEG linker with a DBCO moiety and a terminal maleimide group. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. DBCO is commonly used for copper-free Click Chemistry reactions with azides. The sulfo and PEG chain enhance the water-solubility and biocompatibility of the molecule.
