Description
Sulfo DBCO-PEG4-Amine is a water-soluble carboxyl-reactive building block with an extended PEG spacer arm. In the presence of activators like EDC or HATU, this reagent can be used to derivatize carboxyl groups or activated esters through a stable amide bond.
Applications
Sulfo DBCO-PEG4-Amine is used in bioconjugation and molecular biology research, facilitating copper-free Click Chemistry reactions. Its hydrophilic sulfonated spacer arm greatly improves water solubility and provides a long, flexible connection for modifying biomolecules.
