PKmitoTM benefits

PKmito™ probes feature a unique technology: they consist of cyanine derivatives bearing intramolecular cyclooctatetraene (COT) substituents. The presence of intramolecular COT substituents very efficiently reduces the production of singlet oxygen. Singlet oxygen is a very reactive species produced by fluorophores and it is responsible of rapid cellular damage leading to cell death.

PKmito™ probes therefore allow very gentle imaging of mitochondria in live cells and tissues and preserve them from singlet oxygen damage and phototoxicity.



  • Very low phototoxicity: Allows you to record timelapse STED movies (ca 20 frames) without damaging or changing the mitochondria morphology.

  • Super-resolution Microscopes Compatibility: Can be used for widefield, confocal or STED imaging in living cells and tissue.

  • Very Specific: PKmito ORANGE is the ideal STED probe for mitochondria, staining the inner membrane and therefore revealing mitochondrial cristae (sub diffraction structures impossible to see with conventional microscopes). 

  • Multicolor imaging: Compatible with SIR & SPY probes.
