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.
