General description

3,3′-Dithiodipropionic acid di(N-hydroxysuccinimide ester) (DSP) is a homobifunctional cross-linking reagent containing a cleavable disulfide linkage. It is typically coupled to molecules containing primary amines by amide bonds buffered at pH 7.5 (6.5-8.5).

Application

3,3′-Dithiodipropionic acid di(N-hydroxysuccinimide ester) (DSP) has been used as a protein cross-linker.

Features and Benefits

The disulfide linkage is cleavable by mild reduction.

Caution

Avoid use of reducing agents during coupling reactions.
