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.

Homobifunctional chemical cross-linking reagents are important tools for functional and structural characterization of proteins. Accurate measures of the lengths of these molecules currently are not available, despite their widespread use. Stochastic dynamics calculations now provide quantitative measures of the lengths
