CIL offers the most complete listing of metabolic substrates available. Some of the many applications of these materials include the utilisation of amino acids for protein / amino acid turnover studies, carbohydrates for glucose metabolism studies, and fatty acids for lipolysis reasearch. Isotope labellling of these materials allows investigators to study metabolic pathways in living systems in a manner that is safe and non-invasive.


CIL offer MPT (Microbiological / Pyrogen Tested) products for use in metabolic investigations. These materials are tested for microbial and pyrogen content and have been tested to ensure high chemical purity and isotopic enrichment.

Metabolomics, or the study of biochemical processes involving metabolites, is a relatively new, yet increasingly growing field of research. The use of stable isotopes as internal standards combined with mass spectrometry in metabolomics allows researchers to identify and quantify metabolites in a given biological sample. This information is invaluable to understanding the physiology of an organism and/or its response to a drug, a change in its environment, or other external stimuli.
