3,3′-dihexyloxacarbocyanine iodide (DiOC6) is a supravital lipophilic fluorochrome. This cationic dye is employed to stain mitochondria and endoplasmic reticulum in animal and plant cells. In addition, it acts as a very rapid, consistent and highly selective fluorochrome for endophytic ascomycetes in plant roots and liverworts. DiOC6 also facilitates the detection of different mitochondrial changes happening during early apoptosis.


  • 3,3′-Dihexyloxacarbocyanine iodide has been used
  • to selectively stain endophytic ascomycetes in plant roots and liverworts
  • to visualize thrombus formation and platelet aggregate
  • to visualize forchlorfenuron (FCF)-induced changes in mitochondrial morphology
