CytoTell™ Red 590

Cell tracking assay using CytoTell™ Red 590. Jurkat cells (~2x10^6 cells/mL) were stained with CytoTell™ Red 590 on day 0. Cells were passed serially at 1:1 ratio for 7 days. Fluorescence intensity was measured using FACS Calibur flow cytometer in FL2 channel. Successive generations were represented by different colors.

Flow cytometry combined with fluorescence staining is a powerful tool to analyze heterogeneous cell populations. Among all the existing fluorescent dyes CFSE is the preferred cell proliferation indicator that is widely used for live cell analysis. However, it is impossible to use CFSE and its fluorescein analogs for GFP-transfected cells or for the applications where a FITC-labeled antibody is used since CFSE and its fluorescein analogs have the excitation and emission spectra almost identical to GFP or FITC. CytoTell™ dyes are well excited at major laser lines such as 405 nm, 488 nm or 633 nm with multicolor emissions. CytoTell™ dyes have minimal cytotoxicity, and are used for the multicolor applications with either GFP cell lines or FITC-labeled antibodies since they have either excitation or emission spectra distinct from fluorescein. CytoTell™ Red 590 is a red fluorescent dye that stains cells evenly. As cells divide, the dye is distributed equally between daughter cells that can be measured as successive halving of the fluorescence intensity of the dye. Up to 8 generations may be visualized. CytoTell™ Red 590 can also be used for long term tracking of labeled cells. Analysis using two-parameter plots may provide better resolution of each generation, especially between undivided cells and the first generation. Cells labeled with CytoTell™ Red 590 may be fixed and permeabilized for analysis of intracellular targets using standard formaldehyde-containing fixatives and saponin-based permeabilization buffers. CytoTell™ Red 590 has a peak excitation of 570 nm and can be excited by the yellow (561 nm) laser line. It has a peak emission of 590 nm and can be detected with a 610/20 band pass filter, making it compatible with applications that utilize GFP or FITC antibodies for multicolor cell analysis.

Protocol summary

  1. Prepare cells with test compounds
  2. Add 1X dye working solution
  3. Incubate dyes with cells at room temperature or 37 oC for 10 to 30 minutes
  4. Remove the dye working solution
  5. 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

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.

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

  1. Treat cells with test compounds for a desired period of time.

  2. Centrifuge the cells to get 1-5 × 105 cells per tube.

  3. 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)

  4. Incubate cells with a dye solution at room temperature or 37 °C for 10 to 30 minutes, protected from light.

  5. 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.

  6. Monitor the fluorescence change at respected Ex/Em (see Table 1) with a flow cytometer or a fluorescence microscope.
