  • Product overview

    Abcam's Mitochondrial Transmembrane Potential Apoptosis Detection Kit provides a simple, fluorescent-based method for distinguishing between healthy and apoptotic cells by detecting the changes in the mitochondrial transmembrane potential. The kit utilizes MitoCapture, a cationic dye that fluoresces differently in healthy vs apoptotic cells. In healthy cells, MitoCapture accumulates and aggregates in the mitocondria, giving off a bright red fluorescence. In apoptotic cells, MitoCapture cannot aggregate in the mitochondria due to the altered mitochondrial transmembrane potential, and thus it remains in the cytoplasm in its monomer form, fluorescing green. The fluorescent signals can be easily detected by fluorescence microscopy using a band-pass filter (detects FITC and rhodamine) or analyzed by flow cytometry using FITC channel for green monomers (Ex/Em = 488/530+ 30 nm) and (optional) PI channel for red aggregates (Em = 488/590+ 42 nm).

  • Notes

    Disruption of the mitochondrial transmembrane potential is one of the earliest intracellular events that occur following induction of apoptosis.

  • RelevanceMitochondrial Transmembrane Potential is an important parameter of mitochondrial function used as an indicator of cell death. The collapse of the mitochondrial transmembrane potential coincides with the opening of the mitochondrial permeability transition pores, leading to the release of cytochrome c into the cytosol, which in turn triggers other downstream events in the apoptotic cascade.

You are correct, 1 ml is too much, and the instructions are too vague. You can pipet just a portion of that cell suspension onto a slide, for instance 50 ul, then coverslip. That will be 50,000 cells if you start with one million. If you find that the ...

We assume this assay requires living cells, and that fixation before adding the dye will give unreliable results. However, we have not compared results from fixed and unfixed samples. The question is whether the fixation itself will alter the mitochond...
