Sulfo-SMCC sodium is a water-soluble heterobifunctional crosslinker, consists of a maleimide and an N-hydroxysuccinimide (NHS) ester group to bind to sulfhydryl groups and primary amines, respectively[1]. Sulfo-SMCC sodium is commonly used in the field of bioconjugation, including peptide and protein labeling[2], antibody-drug conjugates (ADCs)[3][4], and labeling biomolecules for detection and imaging[5][6].
