Ordering Information

Biological Activity

Mito-TEMPO is a mitochondria-targeted superoxide dismutase mimetic and scavenger of mitochondrial reactive oxygen species. By selectively scavenging mitochondrial superoxide, it suppresses intra-organellar oxidative stress and prevents peroxynitrite formation. Consequently, Mito-TEMPO treatment attenuates acetaminophen-induced RIP3 kinase expression, restores mitochondrial function, and protects hepatocytes against necrotic cell death in experimental models of acute liver injury.

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 100 mg/mL (196.06 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
Water 100 mg/mL
Ethanol 100 mg/mL
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
