Protocol summary

Prepare cells with test compounds at a density of 5 × 10⁵ to 1 × 10⁶ cells/mL
Prepare and add ThiolTrace^TM Violet 500 working solution to cells
Incubate at 37^oC for 20 to 30 minutes
Read fluorescence intensity at Ex/Em = 405/525 nm-Pacific Orange filter set

Important notes
Thaw at room temperature before starting the experiment.

PREPARATION OF STOCK SOLUTION

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.

ThiolTrace^TM Violet 500 stock solution (500X):
Add 200 µL of DMSO (Component C) into the vial of ThiolTrace^TM Violet 500, and mix well. Note: Aliquot and stored the unused ThiolTrace^TM Violet 500 stock solution at -20^oC. Avoid repeated freeze/thaw cycles.

PREPARATION OF WORKING SOLUTION

ThiolTrace^TM Violet 500 working solution (1X):
Add 2 µL of ThiolTrace^TM Violet 500 stock solution into 1 mL of Assay Buffer (Component B) or buffer of your choice, and mix well. Note: ThiolTrace^TM Violet 500 working solution can be prepared in the cell culture medium containing serum.

SAMPLE EXPERIMENTAL PROTOCOL

Treat cells with test compounds for a desired period of time. Note: For adherent cells, gently lift the cells with 0.5 mM EDTA to keep the cells intact, and wash the cells once with serum-containing media prior to the incubation with ThiolTrace™ Violet working solution. Note: The appropriate incubation time depends on the individual cell type and cell concentration used. Optimize the incubation time for each experiment.
Centrifuge the cells at 1000 rpm for 4 minutes, and wash cells in 1 mL of buffer of your choice (Optional).
Resuspend cells in 1 mL ThiolTrace^TM Violet 500 working solution and incubate them at 37^oC incubator for 20 to 30 minutes.
Monitor the fluorescence intensity with a flow cytometer using Pacific Orange filter set (Ex/Em = 405/525 nm). Gate on the cells of interest, excluding debris.

Figure 1. The decrease in the fluorescence intensity of ThiolTrace™ Violet 500 with the addition of Campothecin in HL-60 cells. HL-60 cells were treated for 6 hours without (Red line) or with 20 μM Campothecin (Green line) in a 37 ^oC, 5% CO₂ incubator, and then stained with ThiolTrace™ Violet 500 for 20 minutes. The fluorescence intensity was measured using ACEA NovoCyte 3000 flow cytometer with Pacific Orange channel.
