Bis-PEG4-NHS ester

Overview

Bis-PEG4-NHS ester is a bi-functional polyethylene glycol (PEG) reagent with two NHS ester groups attached to a PEG4 linker . It is used for bioconjugation by reacting with primary amines on proteins, peptides, or other molecules to form stable amide bonds . Its water-soluble PEG linker enhances flexibility and reduces non-specific binding, making it ideal for protein conjugation , surface modification , and crosslinking in research and clinical applications.
