Peptides labeled with stable, non-radioactive isotopes are increasingly used for convenient detection in research. Isotope–labeled, or ‘heavy’ amino acids, are derived from natural amino acids by substitution of certain atoms (N, C, H) with their ‘heavy isotope’ variant. The most frequently substitutions are 12C by 13C (carbon-13), 14N by 15N (nitrogen-15), and 1H by 2H (deuterium).
10% off is available for stable isotope labeled peptide orders(22nd June 2017 - 31st Dec. 2017). For more details, please contact us at peptide@pepmic.com.
The following are the most frequently requested heavy amino acids, other stable isotope labeled amino acids are available upon request.
