NHS-PEG1-SS-PEG1-NHS (CAT: I015459) is a bifunctional polyethylene glycol (PEG) linker compound that contains two NHS ester groups and a disulfide bond. This linker is designed for conjugating biomolecules, such as proteins or peptides, to surfaces or other molecules. The NHS ester groups react with primary amines on the biomolecules, forming stable amide bonds, while the disulfide bond provides a reversible linkage that can be cleaved under reducing conditions.
