Thermo Scientific Pierce DSP (Lomant's Reagent) is an amine-reactive crosslinker having NHS-ester reactive ends and a cleavable disulfide bond in its spacer arm.

DSP contains an amine-reactive N-hydroxysuccinimide (NHS) ester at each end of an 8-carbon spacer arm. NHS esters react with primary amines at pH 7-9 to form stable amide bonds, along with release of the N-hydroxy-succinimide leaving group. Proteins, including antibodies, generally have several primary amines in the side chain of lysine (K) residues and the N-terminus of each polypeptide that are available as targets for NHS-ester crosslinking reagents. DSS, the non-cleavable analog of DSP crosslinker is also available for applications that require a stable spacer arm that cannot be cleaved in the presence of reducing agents.

DSP Highlights

  • Amine-reactive 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
  • DSP crosslinker is membrane permeable, so intracellular crosslinking can be done
