Partially Labeled Amino Acids

CIL offers a multitude of partially labeled amino acids and derivatives for use in MS- or NMR-based, metabolomics and proteomics research.  The amino acids are canonical (e.g., histidine, proline, threonine) and non-canonical (e.g., beta-alanine, citrulline, ornithine) in grades of research and microbiological/pyrogen tested (MPT), with the isotope labels of variable type (i.e., ¹³C, D, ¹⁵N, ¹⁸O) and position.

Please view the availability, pricing, and specifications of our partially labeled amino acids below and inquire if an alternate compound(s) is required.  Refer to our Stable Isotope Standards for Mass Spectrometry and Stable Isotopes for Biomolecular NMR catalogs for additional information.
