Azido-PEG2-NHS ester (N3-PEG2-SPA) is a PEG derivative containing an azide group and an NHS ester. The hydrophilic polyethylene glycol spacer increases the solubility in aqueous media. The azide group can chemically react with alkynes, BCN, and DBCO to form stable triazole bonds. NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
