DTSSP, 3,3'-Dithiobis （Sulfosuccinimidylpropionate）僅用于科研
Thermo Scientific Pierce DTSSP is a popular water-soluble crosslinker that contains amine-reactive NHS-ester ends around an 8-atom spacer arm, whose central disulfide bond can be cleaved with reducing agents.
3,3´-Dithiobis（sulfosuccinimidylpropionate） （DTSSP） contains an amine-reactive N-hydroxysulfosuccinimide （sulfo-NHS） ester at each end of an 8-carbon spacer arm. Sulfo-NHS esters react with primary amines at pH 7-9 to form stable amide bonds, along with release of the N-hydroxysulfosuccinimide 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 sulfo-NHS-ester crosslinking reagents. DSS, the non-sulfonated analog of DTSSP is also available for applications that require a membrane-permeable crosslinker. BS3, the non-cleavable analog of DTSSP is also available for applications that require a stable spacer arm that cannot be cleaved in the presence of reducing agents.
DTSSP Highlights
- 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
- DTSSP crosslinker is not membrane permeable, so cell-surface crosslinking can be done
