The MitoPT JC-1 Assay detects mitochondrial membrane depolarization utilizing the fluorescent dye JC-1. When accumulated in a negatively charged polarized mitochondria, JC-1 fluoresces orange. When mitochondrial membrane potential collapses in apoptotic or metabolically stressed cells, JC-1 reagent is dispersed through the cell and will fluoresce green. Analyze your results using a flow cytometer, fluorescence plate reader, or fluorescence microscopy.

Bulk Order MitoPT JC-1 Assay

Loss of mitochondrial membrane potential is indicative of apoptosis. ICT’s MitoPT JC-1 Assay utilizes the potentiometric fluorescent dye JC-1 to detect mitochondrial membrane permeability and membrane depolarization. The JC-1 dye has a delocalized positive charge dispersed throughout its molecular structure. In addition, its lipophilic solubility enables it to be readily membrane permeant and penetrate living cells. The JC-1 dye enters the negatively charge mitochondria where it accumulates and fluoresces orange upon excitation. When the mitochondrial membrane potential collapses in apoptotic cells, MitoPT JC-1 becomes distributed throughout the cytosol. Analyze your results using a flow cytometer, fluorescence plate reader, or fluorescence microscopy.

  1. Prepare samples.
  2. Create controls with CCCP.
  3. Dilute 10X Assay Buffer 1:10 with diH2O.
  4. Reconstitute MitoPT JC-1 with DMSO.
  5. Dilute MitoPT JC-1 with 1X Assay Buffer.
  6. Add MitoPT JC-1 to each sample.
  7. Incubate 15-30 minutes.
  8. Wash cells: add 1X Assay Buffer and spin cells (twice).
  9. Analyze with a fluorescence microscope, fluorescence plate reader, or flow cytometer. MitoPT JC-1 excites at 488 nm. Aggregated MitoPT JC-1 (orange) emits at 590 nm, monomeric MitoPT JC-1 (green) emits at 527 nm.
