NucGreen Dead 488 ReadyProbes Reagent Protocol for Fixed Cells
Nuclear stain for fixed cells
NucGreen Dead 488 ReadyProbes Reagent emits bright green fluorescence when bound to DNA and is suitable for staining nuclei in fixed-cell preparations and tissue sections. NucGreen Dead 488 reagent may also be used to measure viability and to measure cytotoxicity in kinetic live-cell assays.
This protocol can be used for:
- Nucleic acid (nuclear) staining in fluorescence microscopy
This protocol should not be used for:
- Flow cytometry
Labeling fixed cells
First, fix and permeabilize cultured cells with a protocol appropriate for your sample.
|1. Wash the cells 1–3 times in PBS as needed.|
|2. Add two drops of NucGreen Dead 488 Reagent per milliliter of medium.|
|3. Incubate for 5–15 minutes, protected from light.|
|4. Remove the stain solution.|
|5. Wash the cells 2–3 times in PBS.|
|6. Image the cells.|

|Standard filter set||FITC or GFP|
|EVOS Light Cube||FITC|
|Storage conditions||Room temperature|
- In some cases, more or fewer drops may be needed to achieve optimal staining intensity.
- Image quality may be improved by replacing the culture medium with Live Cell Imaging Solution (Cat. No. A14291DJ).
