Thermo Scientific™ DSS (disuccinimidyl suberate), No-Weigh™ Format
Shop All Thermo Scientific ProductsDescription
Thermo Scientific™ Pierce DSS, also called disuccinimidyl suberate, is noncleavable and membrane permeable crosslinker that contains an amine-reactive N-hydroxysuccinimide (NHS) ester at each end of an 8-carbon spacer arm.
Highlights:
- Chemical crosslinking of intracellular proteins prior to cell lysis and immunoprecipitation
- “Fix” protein interactions to allow identification of weak or transient protein interactions
- Protein crosslinking to create bioconjugates via single-step reactions
- Crosslink oriented antibodies to Protein A or G agarose
- Immobilize proteins onto amine-coated surfaces

Frequently Asked Questions (FAQs)
No. DSS crosslinks are amide bonds (same as peptide bonds).
We recommend the following buffers: 20 mM sodium phosphate, 0.15 M NaCl, PBS, pH 7.5. Or HEPES, bicarbonate-carbonate and borate buffers may be substituted for PBS. Nearly any non-amine buffer pH 7-8 can be used.
BS3 is the water-soluble analogue of DSS (i.e., DSS is the membrane-permeable analog of BS3). DSS is water-insoluble and membrane-permeable, so it can be used for both intracellular and cell surface crosslinking. BS3 is water-soluble and membrane-impermeable, so it can be used for cell-surface crosslinking.
Any buffer containing primary amines (Tris, glycine, lysine, and ethanolamine) will not work. Glutathione- and imidazole-containing buffers are also not recommended.
The reactive groups are NHS esters that are reactive toward primary amines.
