Mal-PEG-SC, also known as Maleimide-PEG-NHS, is a heterobifunctional PEG derivative consisting of a maleimide group (Mal) and an N-hydroxysuccinimide (NHS) ester group linked by a PEG spacer. The maleimide group selectively reacts with thiol (-SH) groups to form stable thioether bonds, while the NHS ester group reacts with primary amines (-NH2) to form stable amide bonds. Its bifunctional structure allows for the precise and controlled attachment of biomolecules, drugs, or targeting ligands to surfaces, nanoparticles, or other substrates.
