Thermo Scientific Pierce Sulfo-LC-SPDP is a water-soluble, long-chain crosslinker for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form cleavable (reducible) disulfide bonds with cysteines.


  • Reactive groups: NHS ester and pyridyldithiol
  • Reactive towards: amino and sulfhydryl groups
  • Releases a detectable by-product when reacted with a free sulfhydryl group; by measuring the release of pyridine-2-thione at 343 nm, the reaction can be easily followed
  • Water soluble, sulfo-NHS ester reacts rapidly with any primary amine-containing molecule
  • Disulfide bond in the spacer arm is readily cleaved by 10-50 mM DTT or TCEP at pH 8.5
  • Spacer arm is also easily cleaved using reducing SDS-PAGE sample loading buffer
  • Cleavable crosslinker allows separation of crosslinked products
  • Sulfo-LC-SPDP crosslinker is not membrane permeable, allowing cell surface labeling
  • Compare to other varieties of SPDP-type reagents, including pegylated forms


Sulfo-LC-SPDP is Sulfosuccinimidyl 6-(3'-[2-pyridyldithio]-propionamido)hexanoate, a heterobifunctional, thiol-cleavable and membrane impermeable crosslinker. It contains an amine-reactive N-hydroxysuccinimide (NHS) ester that will react with lysine residues to form a stable amide bond. The other end of the spacer arm is terminated in the pyridyl disulfide group that will react with sulfhydryls to form a reversible disulfide bond.
