3,3'-Dithiodipropionic Acid di(N-hydroxysuccinimide ester)

3,3'-Dithiodipropionic acid di(N-hydroxysuccinimide ester) (DSP) is an amine-reactive, cleavable, homobifunctional protein cross-linking reagent. It has been used as a molecular ruler to determine protein tertiary and quaternary structure. DSP has also been used as a component of self-assembled monolayers in gold-based biosensors.Formal Name: 1,1'-bis(2,5-dioxo-1-pyrrolidinyl) ester 3,3'-dithiobis-propanoic acid.
