    • Chemical structure of GMBS (N-succinimidyl 4-maleimidobutyrate), CAS 80307-12-6, ≥98% — a heterobifunctional crosslinker (C12H12N2O6): an amine-reactive NHS ester and a thiol-reactive maleimide on a short aliphatic butyryl spacer. The NHS ester couples to amines and the maleimide to thiols in a two-step conjugation; its aliphatic arm is less immunogenic than aromatic or cyclohexane crosslinkers, favoring hapten-carrier immunogens and enzyme-antibody conjugates. Supplied by NorrChemica with DDP shipping. CoA
