  • Product overview

    Mitochondrial Staining Kit - Green Fluorescence | Cytopainter (ab112143) is designed to label mitochondria in live cells with green fluorescence at Ex/Em = 490/520 nm. The kit uses a proprietary dye that selectively accumulates in mitochondria probably via the mitochondrial membrane potential gradient. The mitochondrial indicator, a hydrophobic compound, easily permeates intact live cells and becomes trapped in mitochondria after it gets into cells. The mitochondrial indicator is retained in mitochondria for a long time since it carries a cell-retaining group. This key feature significantly increases the staining efficiency.

    Abcam's fluorescence imaging kits are a set of fluorescence imaging tools for labeling sub-cellular organelles such as lysosomes, mitochondria, and actin filaments. The selective staining of cell compartments provides a powerful method for studying cellular events in a spatial and temporal context.

  • Notes

    Mitochondria are membrane-enclosed organelles found in most eukaryotic cells. Mitochondria are sometimes described as “cellular power plants” because they generate most of the cellular supply of ATP. In addition to supplying cellular energy, mitochondria are involved in a range of other processes, such as signalling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth. Mitochondria have been implicated in several human diseases, including mitochondrial disorders and cardiac dysfunction, and may play a role in the aging process. Although most of a cellular DNA is contained in the cell nucleus, the mitochondrion has its own independent genome.

1) Most likely not, it is for live cell mitochondria staining.
2) We don't have experiences on Drosophila mitochondria, it should work theoretically.

Sorry for the delay in getting back to you.

As your customer has commented, the live cell mitochondria stain, will also stain the mitochondria of dead cells. The product ab112145 uses a red fluorescent stain for this and will decrease the fluorescence intensity if the cells are apoptotic. The problem with the mitochondrial dyes is that they rely on the cell being live for the dye to accumulate in the cell, therefore using it in fixed tissue as the customer initially asked about would not be compatible. This is why I suggested looking at the F-actin stain as this does work with both live and fixed cells.

I hope this information has been of help. If you have any further questions, please do not hesitate to let me know.

Thank you for your call today and for your enquiry.

As we discussed, I would recommend either ab14744 or ab15895 for immunostaining of mitochondria in mouse cells-



We additionally have a CytoPainter mitochondrial dye, ab112143, that would be suitable to visualize mitochondria in live cells-


I hope this information will be useful, but please let me know if you have any further questions and I'll be happy to help.

Thank you for contacting Abcam.

After you have labeled the live cells with the Cytopainter kit, you can then fix the cells using formaldehyde.

Please let me know if there is anything else I can help you with.

Thank you for your enquiry. The mitochondria dye for ab112143 is for live cells, and can't used after the cells were fixed.  However, our ab112143 kit is fixable (meaning that it labels the live cells, and then the cells can be fixed by formaldehyde, we never use methanol or acetone to fix our cells). Regarding to staining ability, ab112143 stains all the mitochondrias in a cell. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. I am sorry to confirm this kit has not been tested on live cells. We would suggest that incubation with ab112143 for a few hours should be ok, but not for a few days. However, regrettably we are not able to guarantee this as it has not been tested. I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.
