Tool Details

  • Tool name: 4-trifluoromethyl-7-hydrazinyl-2H-chromen-2-one (TFCH) biomolecular fluorophore small molecule (tool compound)
  • Alternate names: TFCH
  • Tool type: Small molecules
  • Tool sub-type: Fluorescent Probe
  • Application: Renal tissue imaging. Live cell screening
  • Description: 4-trifluoromethyl-7-hydrazinyl-2H-chromen-2-one (TFCH) is a novel fluorescent biocompatible probe has been developed to detect oxidative damage in live cells and tissues in as little as 5 minutes. TO accomplish this, TFCH utilizes the irreversible reaction of radicals with biomolecules that result in the covalent addition of carbonyls to biomolecules. This probe has been shown to outperform other commercially available toxicity and reactive oxygen species assays. This probe has been shown to be highly sensitive. The limit of detection is orders of magnitude smaller than other previously reported fluorophores resulting in less reagent needed to detect carbonylation.TFCH is rapid, live cell and tissue compatible and also be used in fixed cells and tissues.
