Protheragen provides a variety of 14C-labeled amino acids to biotech companies and pharmaceutical enterprises. These amino acids include both basic and essential amino acids and are widely used in fields such as protein metabolism research, drug development and evaluation and cell biology.

Our products introduce 14C radioactive isotopes at specific sites within amino acid molecules, such as carboxyl carbon or side chains. The marked sites have stable chemical properties and are not likely to be lost under physiological conditions. If you are interested in our 14C-Amino Acids, please contact us.
