Our Live or Dead™ Fixable Dead Cell Staining Kits are a set of tools for labeling cells for fluorescence microscopic investigations of cellular 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 flow cytometry applications with blue or green laser excitation. The kit uses a proprietary red fluorescent dye that is more fluorescent upon binding to cellular components. The fluorescent dye used in the kit is well excited with the blue (488 nm) and green lasers (532 nm) to fluorescence at 620 nm. 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 flow cytometry applications.

Platform

Components

Example protocol

AT A GLANCE

Protocol Summary

Prepare samples in HHBS (0.5 mL/assay)
Replace with HHBS
Add Stain It™ Red 620 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 Thaw all the components at room temperature before starting the experiment.

CELL PREPARATION

PREPARATION OF STOCK SOLUTIONS

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.

Stain It™ Red 620 stock solution (500X)

Add 200 µL DMSO (Component B) into the vial of Stain It™ Red 620 (Component A) to have 500X Stain It™ Red 620 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™ Red 620 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).

Images

Figure 1. Detection of Jurkat cell viability by Live or Dead™ Fixable Dead Cell Staining Kits 22599. Jurkat cells were treated and stained with Stain IT™ Red 620. Live (violet solid peak) and staurosporine treated (green line) cells were measured with Qdot®605 Channel. The live cell population is easily distinguished from the dead cell population.
