Sulfo DBCO-Amine

Sulfo DBCO-Amine is a water-soluble building block 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. A short spacer arm adds minimal mass to modified molecules.
