Sulfo DBCO-PEG*-Amine is a water-soluble reagent used to derivatize
carboxyl-containing molecules or activated esters (e.g. NHS esters)
with DBCO moiety through a stable amide bond. The hydrophilic
sulfonated spacer arm greatly improves water solubility of DBCO
derivatized molecules, in many cases making it completely soluble
in aqueous media. The PEG spacer arm provides a long and flexible
connection.
