Sulfo-SMCC sodium, a widely utilized non-cleavable, hetero-bifunctional crosslinker for antibody-drug conjugates (ADCs), features both N-hydroxysuccinimide (NHS) ester and maleimide groups. These functionalities enable it to specifically react with primary amines and sulfhydryl groups, respectively.

| Description | Sulfo-SMCC sodium, a widely utilized non-cleavable, hetero-bifunctional crosslinker for antibody-drug conjugates (ADCs), features both N-hydroxysuccinimide (NHS) ester and maleimide groups. These functionalities enable it to specifically react with primary amines and sulfhydryl groups, respectively. |
| In vitro | Sulfo-SMCC, a crosslinker featuring a maleimide group and an N-hydroxysuccinimide ester, is designed to attach to sulfhydryl groups and primary amines, respectively. It effectively prevents the longitudinal fusion of stabilized Microtubules (MTs), which retain a consistent mean length regardless of incubation duration. This has been demonstrated in experiments where MTs, upon treatment with 250 μM Sulfo-SMCC, were observed at intervals of 0 hours, 6 hours, and 24 hours, showing no change in length over time[1]. |
