BS3 crosslinker disodium is a water-soluble, non-cleavable homobifunctional crosslinker with sulfo-NHS ester reactive groups and an 8-carbon spacer. It targets primary amines to form stable amide bonds, enabling efficient protein-protein crosslinking and antibody-drug conjugate synthesis in aqueous conditions. The reagent is provided as a sodium salt and is suitable for bioconjugation, analytical crosslinking, and ADC linker applications.

• Water-soluble, compatible with aqueous reactions.
• Reacts with primary amines to form stable amide bonds.
• Non-cleavable linker for stable conjugates.
• Sulfo-NHS ester groups enable efficient coupling at physiological pH.
• High purity supports reproducible bioconjugation.
• Soluble in DMSO and tested in common in vivo vehicle systems.
• Stable when stored sealed at low temperatures away from moisture and light.
