N-(4,6-divinyl-1,3,5-triazin-2-yl)-PEG8-NHS ester is a novel cysteine binder coupled to a terminal NHS ester bound by a PEG linker. The divinyltriazine rapidly binds two cysteine residues to form macrocyclic peptides under mild conditions. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
