||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 70,000 molecules per cell, assuming a cell dry weight of 0.3 picograms.
