Amino-dPEG®4–t-butyl ester, product number 10221, is a crosslinking reagent consisting of a primary amino group and the tert-butyl ester of a propionic acid group built around a core of monodisperse polyethylene glycol (PEG). The terminal amine reacts with carboxylates to form amide bonds and with aldehydes and ketones to form semi-labile, reducible Schiff bases. Trifluoroacetic acid (TFA) effectively removes the tert-butyl ester protecting group, thus freeing the propionic acid for reaction with amines or formation of an active ester with N-hydroxysuccinimide (NHS) or 2,3,5,6-tetrafluorophenol (TFP).
