BS3 Crosslinker is a water-soluble, non-cleavable, amine-reactive homobifunctional crosslinker (sulfo-NHS ester) designed for bioconjugation and protein crosslinking in aqueous systems. It selectively reacts with primary amines to form stable amide bonds and is commonly used for protein structural studies, surface crosslinking, and as a linker in antibody-drug conjugate research.
- Water-soluble sulfo-NHS ester for use in aqueous buffers.
- Reacts with primary amines to form stable amide bonds.
- Non-cleavable linker for stable, long-lived conjugates.
- Membrane-impermeable, suitable for surface and extracellular crosslinking.
- Useful for bioconjugation, protein structural analysis, and linker development.

Formula: C23H18N2O5, Purity: 97%, MW: 402.4, DBCO-NHS Ester is an amine-reactive compound and can be used to modify an amine-containing molecule in organic solvents (limited solubility in aqueous media). It reacts with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic pH to form covalent bonds. The low mass weight will add minimal spacer to modified molecules.
