Web1 Enriched isotopes have been processed so that, when compared to these same elements that exist in nature, the processed elements contain a higher concentration of atoms with the desired number of neutrons in their nuclei. This subject is discussed in greater detail in the Technical Background section in appendix B. WebISOTEC ® Stable Isotopes are stable isotope compounds, ranging from gases to complex molecules. These compounds are useful for tracer studies in proteomics and metabolomics, agents for MRI / MRS, and in a wide range of other biomedical applications. Both tracer and flux studies benefit from stable isotope label assistance.
