NHS ester PEG
Monodispersed PEG NHS ester is an amine-reactive PEG derivative widely used in bioconjugation with antibodies (ADC), proteins, peptides, and other molecules. The NHS ester group reacts readily with primary amines (NH2) on macromolecules at pH 7-9, forming stable and irreversible amide bonds. This reactivity makes PEG NHS ester a valuable tool in enhancing the stability, solubility, and functionality of bioconjugates in various biomedical and therapeutic applications.
Biopharma PEG offers a wide range of monodispersed NHS ester PEG linkers from lab to commercial scale in both non-GMP and GMP grades. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
