Live or Dead™ Fixable Dead Cell Staining Kit *Deep Red Fluorescence*
Our Live or Dead™ Fixable Dead Cell Staining Kits are a set of tools for labeling cells for fluorescence microscopic investigations of cell functions. The effective labeling of cells provides a powerful method for studying cellular events in a spatial and temporal context. This particular kit is designed to uniformly label fixed mammalian cells in red fluorescence for long term microscopic examination. The kit uses a proprietary red fluorescent dye that is more fluorescent upon bonding to cellular components. The fluorescent dye used in the kit is quite photostable so that the images can be repeatedly examined. The kit provides all the essential components with an optimized cell-labeling protocol. It is an excellent tool for preserving of fluorescent images of particular cells, and can also be used for fluorescence microscope demonstrations.
Example protocol
AT A GLANCE
Protocol summary
- Prepare samples in HHBS (0.5 mL/assay)
- Replace with HHBS
- Add Stain It™ Deep Red to the cell suspension
- Stain the cells at room temperature or 37°C for 20 - 60 minutes
- Wash the cells
- Fix the cells (optional)
- Examine the sample with flow cytometer and/or fluorescence microscope using the appropriate Excitation/Emission filter
Important notes
Thaw all the components 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.
1. Stain It™ Deep Red stock solution (500X):
Add 200 µL DMSO (Component B) into the vial of Stain It™ Deep Red (Component A) to have 500X Stain It™ Deep Red stock solution.

- Prepare cells using 1X Hanks and 20 mM Hepes buffer (HHBS) or sodium azide-free and serum/protein-free buffer of your choice.
- Wash cells once with HHBS or the azide- and serum/protein-free buffer of your choice.
- Resuspend cells at 5 - 10 × 106/mL in HHBS or in the azide- and serum/protein-free buffer of your choice.
- Add 1 µL of 500X Stain It™ Deep Red stock solution to 0.5 mL of cells/assay and mix it well.
- Incubate at room temperature or 37°C, 5% CO2 incubator for 20 - 60 minutes, protected from light. Note: The optimal stain concentrations and incubation time should be experimentally determined for different cell lines.
- Wash cells twice and resuspend cells with HHBS or the buffer of your choice.
- Fix cells as desired (optional).
- Analyze cells with flow cytometer and/or fluorescence microscope using the appropriate Excitation/Emission filter (see Table 1).
