Cell Navigator® Mitochondrion Staining Kit *Red Fluorescence*

Fluorescence images of HeLa cells stained with Cell Navigator® Mitochondrion Staining Kit *Red Fluorescence* using fluorescence microscope with a Texas Red® filter set. Live cells were stained with mitochondria dye MitoLite™ Red (Red). After fixation, the cells were labeled with F-actin dye iFluor® 488-Phalloidin (Cat#23115, Green) and counterstained with Nuclear Blue™ DCS1 (Cat#17548, Blue).

Our Cell Navigator® fluorescence imaging kits are a set of fluorescence imaging tools for labeling sub-cellular organelles such as membranes, lysosomes, mitochondria and nuclei etc. The selective labeling of live cell compartments provides a powerful method for studying cellular events in a spatial and temporal context. This particular kit is designed to label mitochondria of live cells in red fluorescence. The kit uses a proprietary dye that selectively accumulates in mitochondria probably vial the mitochondrial membrane potential gradient. The mitochondrial indicator is a hydrophobic compound that easily permeates intact live cells, and trapped in mitochondria after it gets into cells. This fluorescent mitochondrial indicator is retained in mitochondria for long time since the indicator carries a cell-retaining group. This key feature significantly increases its staining efficiency. The labeling protocol is robust, requiring minimal hands-on time. It can be readily adapted for a wide variety of fluorescence platforms such as microplate assays, immunocytochemistry and flow cytometry. It is useful for a variety of studies, including cell adhesion, chemotaxis, multidrug resistance, cell viability, apoptosis and cytotoxicity. The kit provides all the essential components with an optimized cell-labeling protocol. It is suitable for proliferating and non-proliferating cells, and can be used for both suspension and adherent cells.

Protocol summary

  1. Prepare cells
  2. Add Mitolite™ Red working solution
  3. Incubate at 37°C for 30 minutes to 2 hours
  4. Analyze the cells under fluorescence microscope at Ex/Em = 585/610 nm (Texas Red® filter set)

Important notes
Thaw all the components at room temperature before starting the experiment.

PREPARATION OF WORKING SOLUTION

Add 20 µL of 500X Mitolite™ Red (Component A) into 10 mL of Live Cell Staining Buffer (Component B) to make Mitolite™ Red working solution. Protect from light. Note: 20 µL of 500X Mitolite™ Red (Component A) is enough for one 96-well plate. The optimal concentration of the fluorescent mitochondrial indicator varies depending on the specific application. The staining conditions may be modified according to the particular cell type and the permeability of the cells or tissues to the probe.

SAMPLE EXPERIMENTAL PROTOCOL

For adherent cells:

  1. Grow cells either in a 96-well black wall/clear bottom plate (100 µL/well/96-well plate) or on cover-slips inside a petri dish filled with the appropriate culture medium.

  2. When cells reach the desired confluence, add equal volume of Mitolite™ Red working solution.

  3. Incubate the cells in a 37°C, 5% CO2 incubator for 30 minutes to 2 hours.

  4. Replace Mitolite™ Red working solution with Hanks and 20 mM Hepes buffer (HH buffer) or buffer of your choice (e.g. the buffer with growth medium at 1:1 concentration).

  5. Observe the cells using a fluorescence microscope with Texas Red® filter set (Ex/Em = 585/610 nm). Note: It is recommended to increase either the labeling concentration or the incubation time to allow the dye to accumulate if the cells do not appear to be sufficiently stained.

For suspension cells:

  1. Centrifuge the cells at 1000 rpm for 5 minutes to obtain a cell pellet and aspirate the supernatant.

  2. Resuspend the cell pellets gently in pre-warmed (37°C) growth medium, and add equal volume of Mitolite™ Red working solution.

  3. Incubate the cells in a 37°C, 5% CO2 incubator for 30 minutes to 2 hours.

  4. Replace Mitolite™ Red working solution with Hanks and 20 mM Hepes buffer (HH buffer) or buffer of your choice (e.g. the buffer with growth medium at 1:1 concentration).

  5. Observe the cells using a fluorescence microscope fitted with a Texas Red® filter set (Ex/Em = 585/610 nm). Note: It is recommended to increase either the labeling concentration or the incubation time to allow the dye to accumulate if the cells do not appear to be sufficiently stained. Suspension cells may be attached to cover-slips that have been treated with BD Cell-Tak® (BD Biosciences) and stained as adherent cells.
