Mitophagy Detection Kit

Mitophagy Detection Kit is optimized for mammalian cells.

Mitochondria is one of the cytoplasmic organelle that plays a crucial role in cells such as production of energy for cell viability. Recently, Mitophagy appears to be related to Alzheimer and Parkinson disease induced by the accumulation of depolarized mitochondria. Mitophagy serves as a specific elimination system that dysfunctional mitochondria caused by oxidative stress and DNA damage are sequestered into autophagosome, fused to lysosome and degraded by digestion.
This kit is composed of Mtphagy Dye, reagent for detection of mitophagy, and Lyso Dye. Mtphagy Dye accumulates in intact mitochondria, is immobilized on it with chemical bond and exhibits a weak fluorescence from the influence of surrounding condition. When Mitophagy is induced, the damaged mitochondria fuses to lysosome and then Mtphagy Dye emits a high fluorescence. To confirm the fusion of Mtphagy Dye–labeled mitochondria and lysosome, Lyso Dye included in this kit can be used.

E. Fang etc. detected tomatidine induced mitophagy in HeLa cells by using mt-mKeima. Mitophagy was also detected in both primary rat cortical neurons and human SH-SY5Y neural cells using our Mitophagy Detection Kit. Mitophagy Detection Kit would be a valid alternative method if protein expression/transfection is not ideal for the experiment.
