Sulfo-LC-SPDP protein crosslinking reagent, Sulfosuccinimidyl 6-(3'-[2-pyridyldithio]-propionamido)hexanoate, is one of three SPDP variants produced by ProteoChem (LC-SPDP is the other). Sulfo-LC-SPDP is a cleavable, water soluble, amino and thiol (sulfhydryl) reactive heterobifunctional protein crosslinker. The "long chain" Sulfo-LC-SPDP crosslinking reagent has a 15.7 angstrom spacer arm, and is the water soluble analog of LC-SPDP crosslinker.
Sulfo-LC-SPDP crosslinker's reactive groups include N-hydroxysulfosuccinimide (Sulfo-NHS) ester that reacts with primary amines, as found in lysine side chains; while on the other end of the Sulfo-LC-SPDP crosslinking molecule pyridinyldisulfide reacts with sulhydryls to yield a reversible disulfide bond. The disulfide bond can be reduced with TCEP-HCl or DTT to reverse the crosslinked proteins.
