Common UsePropargyl-PEG4-Maleimide is a PEG derivative containing a propargyl group and a maleimide group. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. The terminal Alkyne will react with azides via copper-catalyzed Click Chemistry. The hydrophilic PEG spacer increases water solubility, allowing easy modification of cysteine containing biomolecules such as antibodies, proteins and peptides with the terminal Alkyne. The PEG spacer will also reduce aggregation of modified proteins stored in solution by adding hydrophilic character.
