15N-MFA

Metabolomics can reflect static metabolite abundance, however, the increases in a single metabolite may be due to activation of synthetic pathways or inhibition of the consumption pathways. Therefore, metabolomics is often insufficient to solve all the issues in the study of specific metabolic pathways and metabolic networks. As a complementary tool to metabolomics, metabolic flux analysis is a powerful tool capable of quantifying energy flow (i.e., ATP, cofactor production and consumption) and their balance. Flux variations for a particular metabolic pathway are not necessarily directly related to metabolite concentrations measured at specific time points within that pathway. However, metabolic flux and metabolic pathway kinetics can be defined via targeting mass spectrometry measurements of substrates and isotopes at continuous time points. In addition to the stable isotope ¹³C, Creative Proteomics also supports the use of ¹⁵N to label specific molecules and track their metabolic processes in the organism to obtain information on the dynamics of metabolites in metabolic pathways.
