Mal-NH-PEG4-NHS functions as a PEG linker comprising a maleimide group and an NHS ester. The hydrophilic PEG spacer enhances solubility in aqueous environments. The NHS ester is suitable for labeling primary amines (-NH2) in proteins, amine-modified oligonucleotides, and other amine-containing compounds. Concurrently, the maleimide group facilitates the formation of a covalent bond by reacting with a thiol group, enabling the linkage of biomolecules to thiols.
