Metabolomics is an increasingly important and growing area of research. The use of stable isotope-labeled standards, in combination with mass spectrometry, allows researchers to identify and quantify metabolites in a given biological sample. This information is used to better understand the physiology of an organism, its response to a drug, a change in its environment, and/or other external stimuli. It is also used to unravel disease mechanisms, assess putative biomarkers, and to monitor metabolic pathway activities (i.e., flux).

To aid such research initiatives, CIL offers a library of isotopically labeled metabolite standards (span a multitude of metabolic classes and pathways) that are available individually and/or as multi-component mixtures and kits. The mixes are formulated neat and/or as solutions and are readily available for immediate use. In addition to the packaged mix(es), the kits include a user manual, which outline general procedures and processing examples for user reference.
