Heterobifunctional protein crosslinking reagents for conjugation between primary amine (lysine) and sulfhydryl (cysteine) groups of proteins and other molecules; available with different lengths and types of spacer arms.
Amine-to-sulfhydryl (lysine-to-cysteine) crosslinking reagents based on N-hydroxysuccinimide and maleimide reactive groups; includes Sulfo-SMCC and forms containing long, polyethylene glycol (PEG) spacer arms.
Amine-to-sulfhydryl (lysine-to-cysteine) crosslinking reagents based on N-hydroxysuccinimide and pyridyldithiol reactive groups; disulfide bond renders the crosslink (spacer arm) cleavable with reducing agents.
