NHS ester PEG

NHS-PEG is a widely used amine-reactive PEG reagent for bioconjugation with antibodies (ADCs), proteins, peptides, and other biomolecules. Its NHS ester group readily reacts with primary amines at pH 7–9 to form stable, irreversible amide bonds.

Biopharma PEG supplies PEG NHS in quantities ranging from milligrams to 100 kg GMP-grade scale to meet diverse R&D and production needs. Contact us at [email protected] for high-quality products to support your next project.
