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.

 

Sulfo-LC-SPDP is Sulfosuccinimidyl 6-(3′-[2-pyridyldithio]-propionamido)hexanoate, a heterobifunctional, thiol-cleavable and membrane permeable 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.

 

Highlights:

  • 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, amine reactive 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 cleaved with 5% β-mercaptoethanol in SDS-PAGE sample loading buffer at 100°C for 5 minutes
  • Cleavable crosslinker allows separation of crosslinked products

     

     

  • Sulfo-LC-SPDP crosslinker is not membrane permeable, so crosslinking can be carried out on the cell surface
