Azido-PEG10-NHS ester linker contains an azide group and an NHS ester. The PEG spacer increases the aqueous solubility of the resulting compound. The azide group readily reacts with alkyne, BCN, DBCO through Click Chemistry to yield a stable triazole linkage. The NHS ester is widely used to label the primary amines (-NH2) of biomolecules such as proteins, oligonucleotides, and etc.
