NH2-PEG36-CH2CH2COOtBu, also known as Amino-PEG36-t-butyl ester, is a heterobifunctional, monodisperse PEG crosslinker that couples carboxylic acids to amines. The crosslinker ends with an amine-reactive, tert-butyl ester-protected propionic acid at one end. The tert-butyl ester protecting group can be cleaved with trifluoroacetic acid (TFA). Once cleaved, the exposed acid reacts with the amine to form an amide bond. The other end is terminated with a carbonyl-reactive primary amine.
