Bis-PEG13-NHS ester is a PEG derivative containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. PEG Linkers may be useful in the development of antibody drug conjugates.
