Mitochondria Research

Mitochondria research is very multi-faceted, because the multi-functional organelle is not only involved in energy production in a cell, but other additional cellular functions. The active cycle of mitochondrial fusion and division induces morphological changes, which is called mitochondrial dynamics. Abnormalities in morphological control of mitochondria are associated with neurodegenerative diseases, metabolic disorders, aging, and so on. Therefore, the demand for long-term observation of mitochondrial dynamics has recently been increasing.

Selection Guide of Reagents

The following table lists reagents for mitochondrial research designed to stain and detect mitochondria (MitoBright LT, MitoTracker, etc.), mitochondrial membrane potential (JC-1, TMRM, TMRE, etc.), reactive oxygen species AKA ‘ROS’ (mtSOX, MitoSOX, etc.), mitophagy, and lipid peroxides.

Mitophagy

Mitophagy
Reagent Mtphagy Dye Keima-Red
Principle Mtphagy Dye (included in Mitophagy Detection Kit) is a pH-sensitive fluorescent probe that accumulates in mitochondria and emits red fluorescence due to acidic conditions in a lysosome. A pH-sentitive ratiometric fluorescent protein. The excitation spectrum changes accoring to pH. This protein shows high fluorescence ratio (Ex. 550 nm/440 nm) values in a lysozome.

Lipophilic peroxide / Singlet oxygen / Superoxide

  Lipophilic peroxide Singlet oxygen Superoxide  
Reagent MitoPeDPP Si-DMA mtSOX Deep Red MitoSOX
Principle A cell-permeant fluorescent probe that accumulates in mitochondria and specifically reacts with lipophilic peroxides in mitochondria to emit fluorescence. A cell-permeant fluorescent probe that accumulates in mitochondria and specifically reacts with singlet oxigen generated in mitochondria to emit red fluorescence. A cell-permeant fluorescent probe that accumulates in mitochondria and reacts with superoxide generated in mitochondria to emit fluorescence. A cell-permeant fluorescent probe that accumulates in mitochondria and reacts with superoxide generated in mitochondria to emit red fluorescence.

Membrane potential

Membrane potential
Reagent JC-1 MT-1 TMRM, TMRE
Principle A cell-permeant ratiometric fluorescent dye that accumulates in intact mitochondria due to the membrane potential. The excitation spectrum changes according to the mitochondria membrane potential. Cell-permeant fluorescent dyes that accumulate in intact mitochondria due to the membrane potential. MT-1 is extremely photostable and more sensitive than JC-1 and can provide equivalent detection sensitivity to TMRE. Cell-permeant fluorescent dyes that accumulate in intact mitochondria due to the membrane potential. Diffusion of the probes occurs in a damaged mitochondria that has the decreased membrane potential.
