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.

Disclaimer

Avoid use of reducing agents during coupling reactions.

Exposure of gold surfaces to solutions of dithiobis N-succinimidyl propionate (DTSP) gives rise to the modification of the surface with N-succinimidyl-3-thiopropionate (NSTP) which can, in turn, react with amino groups allowing for the covalent immobilization of enzymes such as horseradish

Disulfide-linked gold nanoparticles (AuNP) were synthesized by reacting dithiobis[succinimidylpropionate] (DSP) coated nanoparticles with glutathione disulfide. AuNP-cross-linking was monitored by the red shift and broadening of the AuNP's localized surface plasmon absorption resonance (LSPR) spectrum. The exposure of the disulfide-linked AuNPs

This paper reports on an ultrasensitive, disposable, impedimetric biosensor for cortisol detection. C-Mab (a Cortisol specific monoclonal antibody) was covalently immobilized via amide bond on the surface of the interdigitated micro-electrodes (IDmicroEs) functionalized with dithiobis(succinimidyl propionate) (DTSP) self-assembled monolayer (SAM).
