Metabolism cannot be studied thoroughly by measuring metabolite concentrations by metabolomics. Equally important is understanding the activity of pathways, so scientists quantify metabolic pathways in terms of the flow of material per unit of time, i.e., metabolic flux. Metabolic pathways are enzyme-mediated biochemical reactions that lead to biosynthesis (anabolism) or breakdown (catabolism) of natural product small molecules within a cell or tissue. Metabolic pathway analysis, a methodology used in metabolic pathway modeling, is widely used to assess inherent network properties and identify meaningful structural and functional units in the metabolic networks.

Our Services

Creative Proteomics has developed a novel metabolic flux analysis platform to provide metabolic pathways study service in a competitive fashion. We can offer a wide range of services to support all research and development activities.

Identification of metabolic pathway

In metabolomics, identification of metabolic pathways is essential to reveal the underlying biological mechanisms. With the aim of facilitate biological interpretation, our teams have already developed a metabolic pathway identification approach that incorporates all pathways into a global model. And our method is able to identify significant metabolic pathways that contribute to the biological interpretation of metabolomics data.

Discovery of new pathway

Discovery of new metabolic pathways can be achieved by tracking the distribution of heavy atoms from isotopes in the metabolic networks.

Network-wide pathway elucidation

Stable isotope labeled metabolite analysis enables the identification of metabolic pathways, providing direct information on novel metabolic pathways. By combining untargeted (or semitargeted) metabolomics with stable isotope labeling, Creative Proteomics has developed a diversity of tools for network-wide pathway elucidation, which in turn accurately identifies and quantifies hundreds of known metabolites. This approach provides the potential for discovering new metabolic pathways and reveals important information about the active pathways of organisms with multiple possible carbon sources.

The network-wide isotope-labeled metabolomics data can be gained by collection of time-course data, to trace the incorporation of metabolites or by using partially labeled or mixed labeled/unlabeled isotopic precursors
