Description Features and Benefits Fmoc-N-amido-dPEG®24-acid is a novel Fmoc-protected amino acid containing a single molecular weight PEG (dPEG®) spacer arm. This reagent is used to introduce a hydrophilic, non-immunogenic spacer into a peptide (89 Å). Three different lengths of dPEG® allow precise control of spacing and hydrophilicity. Fmoc group can be removed, exposing the terminal amine, using piperidine as with standard peptide synthesis.
