Protected Amino Acids

Stable Isotope Labeled Protected Amino Acids for Peptide Synthesis

Protected amino acids allow for the precise control of the position of labeled amino acids within a peptide of interest allowing researchers to address structural questions. This type of tool can be extremely beneficial in the analysis of membrane proteins, self associating proteins forming insoluble deposits and macromolecular structures. ISOTEC Stable Isotopes offers a wide selection of both Fmoc and t-Boc protected amino acids for this application.
