    Metabolism Flux Assessment Service

      Metabolic Flux Analysis (MFA) uses stable isotope-labeled precursors like glucose and amino acids to study cellular metabolic activities. This approach allows us to infer the pathways, transformation rates, and distribution of metabolites by analyzing their isotopic labeling patterns. MFA provides dynamic insights into the metabolism of cells under various physiological and pathological conditions, offering a deeper understanding of metabolic pathway activities and their biological impacts.

      Services at MtoZ Biolabs

      At MtoZ Biolabs, we combine metabolic flux analysis with cutting-edge metabolomics technologies to explore changes, flows, and rates within cellular metabolic networks. This analysis helps us identify critical metabolic irregularities and their regulatory mechanisms, providing essential scientific insights for disease mechanism studies, drug target identification, and validation.

      1. Isotope Labeling Techniques

      We utilize a range of stable isotope-labeled precursors, including:

      • [U-13C6] glucose, [U-13C5] glutamine
      • [13C5,15N2] glutamine, [13C4] aspartate
      • Deuterated metabolites, like deuterium-labeled alcohol



      2. Metabolic Pathway Analysis

      • We focus on key pathways such as glycolysis, the tricarboxylic acid cycle, and the pentose phosphate pathway, as well as the dynamics of amino acids, fatty acids, and one-carbon metabolism.
      • Our studies also encompass energy metabolism, particularly the production and use of NADPH.
