Azido-PEG2-PFP ester linker contains azide and PFP ester moities.The azide group readily reacts with alkyne, BCN, DBCO through Click Chemistry to yield a stable triazole linkage. The PFP ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Unlike NHS ester, the PFP ester is less susceptible toward hydrolysis.
