Protocol summary
- Prepare cells with test compounds
- Add 1X dye working solution
- Incubate dyes with cells at room temperature or 37 oC for 10 to 30 minutes
- Remove the dye working solution
- Analyse with flow cytometer with appropriate filter set
Important notes
Bring all the kit components at room temperature before starting the experiment. Note: The CytoTell™ dyes are lyophilized powders. They should be stable for at least 6 months if store at -20 °C, protecting from light, and avoiding freeze/thaw cycles.

PREPARATION OF STOCK SOLUTION
CytoTell™ dye stock solution (500X):
Add 500 µL DMSO into the dye powder vial, mix it well by vortexing to have a stock solution (500X). Note: The stock solution should be used promptly; any remaining solution should be aliquoted and frozen at < - 20 oC. Avoid repeated freeze-thaw cycles, and protect from light.
PREPARATION OF WORKING SOLUTION
CytoTellTM dye working solution (1X):
Dilute the 500X DMSO stock solution at 1 to 500 in Hanks and 20 mM Hepes buffer (HHBS) or the buffer of your choice, pH 7 (such as 1 µL of 500X DMSO stock solution to 500 µL buffer) right before use. Mix them well by vortexing. Note: The final concentration of the dye working solution should be empirically determined for different cell types and/or experimental conditions. It is recommended to test at the concentrations that are at least over ten fold range. Such as CytoTell™ Red might use much less amount in some cell types than the recommend concentrations.
SAMPLE EXPERIMENTAL PROTOCOL
- Treat cells with test compounds for a desired period of time.
- Centrifuge the cells to get 1-5 × 105 cells per tube.
- Resuspend cells in 500 µL of the CytoTell™ dye working solution. Optional: One can add the 500X DMSO stock solution into the cells directly without medium removing (such as, add 1 µL500X DMSO stock solution into 500 µL cells)
- Incubate cells with a dye solution at room temperature or 37 °C for 10 to 30 minutes, protected from light.
- Remove the dye working solution from the cells, wash the cells with HHBS or buffer of your choice. Resuspend cells in 500 µL of pre-warmed HHBS or medium to get 1-5 × 105 cells per tube.
- Monitor the fluorescence change at respected Ex/Em (see Table 1) with a flow cytometer or a fluorescence microscope.
