HaloTag-RealThiol (HaloRT) Universal Organelle Specific Glutathione (GSH) Probe

The Halo-RealThiol (HaloRT) probe provides ratiometric fluorescent readout for quantification of glutathione in live mammalian cells.

Highlights:

  • HaloRT is cell permeable and can measure GSH levels in any organelle of interest
  • Conveniently compare organelle-specific GSH levels in live cells using confocal microscopy
  • Signals from blue and green channels allow for deduction of organelle specific GSH concentration, given appropriate calibration curve
  • Validated in the nucleus, cytosol, mitochondria, and endoplasmic reticulum (ER) in HeLa cells
  • This item is HaloRT ligand and must be used in cells expressing HaloTag protein

Subcellular detection and localization of GSH is important in understanding the modulation of redox status, the effect of drugs, and the mechanisms of detoxification. Furthermore, differences in GSH levels in response to oxidative stress in subpopulations of cells have been reported, underscoring the importance of detection methods amenable to flow cytometry and automated fluorescence detection.
