Hydroxy-dPEG®₄-TFP ester

Hydroxy-dPEG®4-TFP ester, product number 11341, is a hydroxy-terminated, single molecular weight, discrete polyethylene glycol (dPEG®) compound that has a 2,3,5,6-tetrafluorophenyl (TFP) ester for conjugation to primary and secondary amines. TFP esters outperform traditional N-hydroxysuccinimide (NHS) esters, because TFP esters are less susceptible to hydrolysis and more reactive towards primary and secondary amines than NHS esters. This product can be used for modification of amine-functionalized surfaces (e.g., silica, glass), modification of proteins and peptides at accessible amine sites on the molecules, the construction of discrete PEG dendrimers, and many other applications.
