Sulfo DBCO-PEG4-Maleimide is a water-soluble, sulfhydryl-reactive reagent that enables simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing molecules. The hydrophilic sulfonated spacer arm greatly improves water solubility of DBCO derivatized molecules, in many cases making it completely soluble in aqueous media. The hydrophilic PEG spacer arm improves labeling efficiency and provides a long and flexible connection.
