For solid-phase peptide synthesis or as a protected linker, our Fmoc-N-amido-dPEG®x-NHS ester products provide superb performance without the need to activate the dPEG® linker before using it. Available in three popular dPEG® chain lengths (4, 8, and 12), these Fmoc-protected amino-dPEG®-acid compounds increase the hydrophilicity and hydrodynamic volume of peptides. Moreover, they impart flexibility to peptide chains when incorporated into the middle of the peptide sequence. The N-hydroxysuccinimide (NHS) ester reacts rapidly with primary amines at neutral pH. The Fmoc protecting group removes easily from the N-terminus of the dPEG® linker using piperidine but remains stable in the presence of TFA.
Try our Fmoc-N-amido-dPEG®x-NHS ester products today and discover the dPEG® difference in your syntheses.
