About Silantes

Silantes - Your partner for stable isotope labelled Biomolecules


We produce and distribute uniformly and partially stable isotope labeled biomolecules. These are +98% isotopically enriched in each variation of the stable isotopes 2H, 13C and 15N.

With this portfolio, we serve both applications nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (proteomics) with products and solutions that lead up to precise results. Our vision is to broaden the applications for stable isotope labeled biomolecules.


The Story of the Silantes Technology

Silantes uses a new biotechnological approach to produce biomolecules such as amino acids, nucleotides, peptides, proteins and DNA labeled with the stable isotopes 2H, 13C and 15N.

This technology was developed in 1998 by Dr. Hermann Heumann in the German Max-Planck-Institute of Biochemistry - the birth of Silantes.

The technology exploits the fact that chemolithoautotrophic bacteria can metabolise inorganic carbon in a pathway similar to that of green plants. Chemolithoautotrophic bacteria combine the advantage of green plants of being able to assimilate COwith the advantage that bacteria are more productive and are also capable of expressing heterologous proteins.

The labeled chemolithoautotrophic bacteria cells are used as a factory to produce the stable isotope labeled biomolecules of choice. This pioneering technology provides an outstanding homogeneity of components labeled with stable isotopes, especially in the area of triple labeled (2H, 13C and 15N) biomolecules.
