DBCO-sulfo-PEG9-acid functions as a bifunctional PEG linker with a DBCO moiety to react with azide-tagged molecules via click chemistry and an acid moiety to react with amine-bearing entities in the presence of activators such as HATU. The PEG9 units and sulfo group both enhance the compound's solubility in aqueous media. Reagent grade, for research use only.
