Learn More About Protected Amino Acids
Fmoc- and Boc-protected amino acids are the core building blocks of solid-phase peptide synthesis (SPPS). Introducing a stable isotope label — 13C, 15N, or deuterium — at a defined position lets researchers track the resulting peptide by NMR, or use it as an internal standard for accurate quantitation by mass spectrometry.
Eurisotop's protected amino acid range spans single-site to uniformly labeled derivatives, in a choice of protecting groups and preloaded resins, to fit directly into existing SPPS workflows. To explore our complete range, please visit our dedicated category page: Protected Amino Acids — Eurisotop.
