MitoPT TMRM Assay 使用螢光染料 TMRM 檢測線粒體膜去極化。當累積在帶負電荷的極化線粒體中時,TMRM 會發出橙色螢光。當凋亡或代謝應激細胞中的線粒體膜電位崩潰時,TMRM 試劑分散在細胞質中,螢光水平急劇下降。使用流式細胞儀、螢光盤式分析儀或螢光顯微鏡分析您的結果。


Loss of mitochondrial membrane potential is indicative of apoptosis. ICT’s MitoPT TMRM Assay utilizes the potentiometric fluorescent dye TMRM to detect mitochondrial membrane permeability and membrane depolarization. The TMRM 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 TMRM dye enters the negatively charge mitochondria where it accumulates and fluoresces orange upon excitation. When the mitochondrial membrane potential collapses in apoptotic cells, MitoPT TMRM becomes distributed throughout the cytosol. Detection of the loss of orange-red fluorescence in TMRM stained cells is a reliable method for assessing apoptosis induction or oxidative stress-induced mitochondrial depolarization in experimental cell populations.

  1. Prepare samples.

  2. Create controls with CCCP.

  3. Dilute 10X Assay Buffer 1:10 with diH2O.

  4. Reconstitute MitoPT TMRM with DMSO.

  5. Dilute MitoPT TMRM with 1X Assay Buffer.

  6. Add MitoPT TMRM to each sample.

  7. Incubate 15-30 minutes.
