CloudReadyProbes® Cell Viability Imaging Kit (Blue/Green) Protocol
Two-color nuclear staining assay for cell viability
This kit can be used to quickly and easily determine the viability of cells. NucBlue® Live reagent stains the nuclei of all cells, while NucGreen® Dead reagent stains only the nuclei of dead cells.
This protocol can be used for:
- Identifying live and dead cells using a fluorescence microscope
This protocol should not be used for:
- Flow cytometry
You will need the following for this protocol:
- Cells growing in culture
- ReadyProbes® Cell Viability Imaging Kit, Blue/Green (Cat. No. R37609)
- Fluorescence microscope with DAPI and FITC filters
Protocol
 1. Culture cells in appropriate medium and vessel for microscopy |
 2. Add 2 drops each NucBlue® Live and NucGreen® Dead reagents per milliliter of medium to label cells |
 3. Incubate 5–30 minutes |
 4. Image cells |
Spectral information and storage
| NucBlue® Live | NucGreen® Dead | |
|---|---|---|
| Excitation/Emission | 360/460 nm | 504/523 nm |
| Standard filter set | DAPI | FITC/GFP |
| EVOS® Light Cube | DAPI | GFP |
| Storage conditions | Room temperature | Room temperature |
Protocol tips
- In some cases, more or fewer drops may be needed to achieve optimal staining intensity
- Image quality may be improved by replacing media with Live Cell Imaging Solution (Cat. No. A14291DJ)
