概要

Bis-PEG5-NHS ester is a PEG derivative containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.

Features and Benefits
· Reactive groups: 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
