Customer Reviews

Based on customer reviews.

Sample solution is provided at 25 µL, 10mM.

Description

CytoTrace Red CMTPX is a fluorogenic dye used as a long-term cell tracer. It is nonfluorescent but cell-permeant and, upon entering the cell, is converted to a fluorescent compound in the cytosol. CytoTrace Red CMTPX is retained by living cells and displays excitation/emission spectra of 577/602 nm, respectively. It remains fluorescent for at least 72 hours and is retained through cell division for several cycles.

实验参考方法

NOTE: The following is a recommended protocol and only provides a guideline. lt should be modified according to specific lab needs.

1. Prepare a 2-10 mM DMSO stock solution.

NOTE: The stock solution should be used promptly; any remaining solution should be aliquoted and frozen at -20°C. Avoid repeated freeze-thaw cycles and protect from light.

2. Prepare a dye working solution.

Prepare a 1-20 μM dye working solution immediately before use by diluting the DMSO stock solution from Step 1 with Hanks' and 20 mM HEPES buffer (HHBS), or the buffer of your choice, at pH 7.0. Mix well by vortexing.

3. Analyze cells with a flow cytometer or a fluorescence microscope:

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

b. Centrifuge cells to obtain 2-10 x 105 cells per tube.

c. Resuspend cells in 500 ul of the dye working solution (from Step 2).

d. Incubate cells with dye solution at room temperature or 37°C for 15 to 30 minutes, protected from light.

e. Remove the dye working solution from the cells and wash the cells with HHBS or buffer of your choice.

f. Resuspend cells in 500 ul pre-warmed HHBS or medium to get 2-10 x 105 cells per tube.

g. Monitor the fluorescence at excitation and emission wavelengths of 577 and 602 nm, respectively, with a flow cytometer (FL1 channel) or a fluorescence microscope.

NOTE for bacterial cell staining: Staining is most efficient when the stock dye solution is diluted 1:800 in nutrient broth preconditioned by overnight growth of the test bacteria, but fresh nutrient broth or PBs may also be used. Bacterial suspensions should be diluted with PBS to 105-107 organisms per ml. Bacteria may be stained by applying one ml of solution to a 0.45 μm filter (25 mm, vacuum filtering to remove the solution, then adding 1 ml of dye solution and incubating 5 to 10 minutes at room temperature.
