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.

Bis-PEG4-NHS ester, CAS 1314378-11-4, is a dual-function polyethylene glycol (PEG) reagent used in bioconjugation. It features a PEG4 linker, which consists of four ethylene glycol units, with NHS ester groups on both ends. These NHS esters are highly reactive with primary amines found on proteins, peptides, and other biomolecules, allowing them to form stable amide bonds.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
