BS(PEG)9 is a bis-succinimide ester-activated PEG compound used for crosslinking between primary amines (—NH2) in proteins and other molecules. The N-hydroxysuccinimide ester (NHS) groups at either end of the PEG9 spacer react specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds.

Features of BS(PEG)9:

Reactive groups: sulfo-NHS ester (both ends)
Reactive towards: amino groups (primary amines)
• NHS esters react with—NH2 groups at pH 7-9, forming stable amide bonds
• Water-soluble; compare to non-pegylated BS3 (also soluble) and DSS (water-insoluble)
• Membrane-impermeable, allowing for cell surface labeling
• Irreversibly crosslink proteins or peptides by flexible PEG spacer arms
• Polyethylene glycol spacer arms help maintain conjugate solubility
• Pure compound with defined structure and molecular weight, ensuring reproducible protein-modification effects
• PEG spacer provides unique advantages, including increased stability, reduced tendency toward aggregation and reduced immunogenicity
• Ideal for small molecule or peptide conjugations

Alternative Names for BS(PEG)n:

• Bis-NHS-dPEG
• NHS-PEG-NHS
• BS(PEO)5
• Bis(NHS)PEO5
• BS-PEO9
• dPEG NHS ester
• Bis-succinimide ester PEG 400
