Stable Isotope Labeling Services

With the progress of science, novel stable isotope-labeled substrates are needed in fields such as medicine, agriculture, environmental sciences and life sciences. Stable isotope-labeled techniques include tracers for clinical research, labeled amino acids for quantitative proteomics, and standards for metabolism research.

BOC Sciences is a supplier of stable isotope-labeled compounds, and we have been researching the development and production of stable isotopes as well as stable isotope-labeled compounds. Whether stock products or customized production services, our experienced professional scientists can find the best solution for you. Currently, our available stable isotopic labels include carbon-13, nitrogen-15, deuterium, and oxygen-18. We are committed to completing the multi-step synthesis of stable isotope-labeled compounds with a variety of labeling modes, including:

  • Labeled Impurities
  • Labeled Inhibitors
  • Labeled Metabolites
  • Labeled Polymers
  • Labeled Steroids
  • Labeled Vitamins
  • NMR Solvents and Consumables
  • Labeled Amino Acids
  • Labeled Peptides
  • Labeled Nucleic Acids
  • Labeled APIs
  • Labeled Building Blocks
  • Labeled Carbohydrates
  • Labeled Fatty Acids & Lipids¬†


Isotopes refer to elements of the same atomic number (number of protons) but different mass numbers (number of neutrons). A stable isotope is a type of isotope whose radioactivity cannot be detected by naturally occurring techniques. In nature, the chemical and biological properties of stable isotopes compounds and the corresponding elements compounds are identical except for the mass number. Thus, the use of stable isotopes in labeled compounds synthesis (such as labeled amino acids, labeled peptides, labeled nucleic acids, etc.) can act as tracers. Analytical instruments such as nuclear magnetism, mass spectrometry, and gas chromatography are used to measure isotope ratio changes and thereby reveal the reaction pathaway and action mechanism.
