Protected Amino Acids

Stable Isotope Labeled Protected Amino Acids

Protected amino acids are amino acids that have been chemically modified to temporarily block (or “protect”) reactive functional groups โ€” typically used during peptide synthesis, especially in solid phase peptide synthesis (SPPS). Protection prevents unwanted side reactions during the stepwise construction of peptides. Silantes supplies stable isotope-labeled protected amino acids specifically designed for use in SPPS, with reagents designed to enable precise incorporation of isotope-labeled residues at defined positions within the peptide sequence.
