Alkyne-PEG4-Maleimide enables simple and efficient incorporation of terminal alkyne group onto antibodies, cysteine-containing peptides and other thiol-containing molecules. The hydrophilic polyethylene glycol (PEG) spacer arm imparts solubility in aqueous buffers, and provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.
