FmocNH-PEG-NHFmoc

Alpha,omega-bis(fluorenylmethoxycarbonyl-protected amino) poly(ethylene glycol) (FmocNH-PEG-NHFmoc) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear Fmoc-protected amine groups. Discrete chain lengths with different degrees of polymerization are available. Fmoc protection facilitates sequential conjugation. Amine coupling can follow deprotection under conditions compatible with the target system. Identical reactive sites at both ends support molecular bridging or derivatization on both sides. The conjugation scheme can be designed around the number of target sites.
