IROA utilizes full metabolic labeling to distinguish between two cell populations, specifically both 5% 13C (to label experimental samples) and 95% 13C (to label control samples). How is this achieved? Compounds are randomly and universally labeled to achieve this effect. The relative abundances of the isotopes of carbon are altered; i.e. enriched in one particular isotope and depleted in its other isotopic form. For example, 95% U-13C6-Glucose is not actually 95% 13C6 and 5% 12C6. In this case, each carbon atom position (1,2,3,4,5,6) has a 95% chance of being 13C labeled and a 5% chance of being 12C. Compounds such as 5% and 95% U-13C6-Glucose are produced especially for IROA Technologies LLC by Cambridge Isotope Technologies, Inc.
