Description

NH2-PEG8-acid features a terminal amine and carboxylic acid group separated by an eight-ethylene glycol unit spacer. This bifunctional architecture enables conjugation to diverse biomolecules or surfaces via amine-reactive and carboxylate-compatible chemistries. The PEG8 chain imparts solubility and reduces non-specific binding in biological environments.

Application

NH₂-PEG₈-acid serves as a versatile bifunctional linker for conjugation workflows, combining the solubility and stability of a long-chain PEG spacer with reactive amine and carboxylic acid termini. It enables efficient coupling to biomolecules via amide bond formation or NHS ester activation, facilitating applications in antibody-drug conjugates, peptide-protein labeling, and surface functionalization. The PEG8 chain enhances hydrophilicity and reduces non-specific binding, while the terminal groups offer predictable reactivity under standard conditions.
