Ordering Information

Biological Activity

FCCP is a potent protonophore uncoupler of mitochondrial oxidative phosphorylation. By transporting protons across lipid membranes, it rapidly dissipates the mitochondrial membrane potential and collapses the transmembrane proton gradient, thereby decoupling oxygen consumption from ATP synthesis. Consequently, FCCP-induced mitochondrial depolarization disrupts cellular energy metabolism, stimulates respiration rates, and triggers selective autophagosomal degradation of dysfunctional mitochondria through mitophagy.

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).
