Abstract

13C labeling dynamics of intra- and extracellular metabolites in CHO suspension cells

Highlights

  • Isotope labeling techniques have become a most valuable tool in metabolomics and fluxomics [1]

  • Aspartate, and glutamine were only consumed, we found significant extracellular labeling of these metabolites indicating simultaneous consumption and excretion

  • Significant labeling of serine and glycine was found on labeled glucose but not on labeled glutamine indicating the absence of gluconeogenesis
