Uniformly Labeled Protected Amino Acids

CIL offers a variety of uniformly labeled, protected amino acids for solid phase peptide synthesis. The side chain protected groups are N-Fmoc or -Boc, while the amino acids are canonical (e.g., L-Arginine or Arg, L-Isoleucine or Iso, L-Phenylalanine or Phe, L-Valine or Val) and the labeled isotope is variable (i.e., ¹³C, D, ¹⁵N).

Please view the availability, pricing, and specifications of our uniformly labeled, protected amino acids below and inquire if alternate starting materials are required. Additional information is provided in our Stable Isotope-Labeled Peptide and Protein Reagents/Kits catalog.
