Amino Acids and Derivatives

In structural genomics, the use of biomolecular NMR to study protein structure and function relies heavily on the use of stable isotope labeled proteins. In order to incorporate the stable isotope label into these proteins, researchers use labeled amino acids in a variety of methods that include peptide synthesis, cell-free protein synthesis, and microbial growth by media. Labeled amino acids provide the ability to incorporate ¹³C, ¹⁵N, and/or deuterium labels into the protein allowing the user a significant level of flexibility to create uniform, selective, or site-specific labeling patterns throughout the protein structure.

ISOTEC Stable Isotopes offers a full line of protected and unprotected amino acids labeled with ¹³C, ¹⁵N and/or deuterium. Our complete product line includes amino acid mixtures as well as all twenty amino acids with a variety of labeling patterns for all of your research needs.
