||Researchers introduce kinetic flux profiling (KFP), a variant of metabolic flux profiling that involves monitoring the dynamics of incorporation of isotope-labeled nutrient into downstream products using LC-MS/MS. The essential concept of KFP is that intracellular metabolites become labeled when cells are switched from unlabeled to isotope labeled nutrient, and metabolites closer to the added nutrient in the metabolic network always get labeled before their downstream products.
||The units of g refers to gram cell dry weight. This is equivalent to approximately 1,200,000 molecules per cell, assuming a cell dry weight of 0.3 picograms.
