Flux-analysis

Flux-analysis // Tobias Kind June 2017

Metabolic flux analysis investigates specific metabolites in metabolic pathways by utilizing stable isotopic markers.
Commonly used markers include 13C and 15N that are integrated into specific metabolites (WIKI)

Isotope labelled compound vendors

For finding isotope labellec compounds and best prices from various companies it is best to search meta-indexes first.
That includes CAS Scifinder, emolecules, Chemspider and MolBase. 

  • eMolecules (free chemical search engine with hundres of vendors [LINK]
  • CAS Scifincer (12 million commercial chemical products) [LINK]
  • MolBase (find chemicals and prices by name or CAS number [LINK]
  • ChemSpider (limited vendor support) [LINK]
