Sulfo DBCO-Maleimide a water-soluble 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. A short spacer arm adds minimal mass to modified molecules.
A water-soluble, sulfhydryl-reactive labeling reagent with PEG4 spacer arm.
