僅用于科研
Thermo Scientific Pierce SPDP is a short-chain crosslinker for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form cleavable (reducible) disulfide bonds with cysteine sulfhydryls.
Thermo Scientific Pierce LC-SPDP is a long-chain crosslinker for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form cleavable (reducible) disulfide bonds with cysteine sulfhydryls.
We offer three analogs of SPDP: the standard version (SPDP), a derivative with a longer spacer arm (LC-SPDP) and Sulfo-LC-SPDP, the sulfonated analog of LC-SPDP is available for applications that require a water-soluble, membrane-impermeable crosslinker. SPDP (N -Succinimidyl 3-(2-pyridyldithio)-propionate) and LC-SPDP (Succinimidyl 6-(3-[2-pyridyldithio]-propionamido)hexanoate) are heterobifunctional, thiol-cleavable and membrane permeable crosslinkers. They each contain 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
- 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
- SPDP crosslinker is membrane permeable, so crosslinking can be carried out inside the cell
