Propidium iodide (PI) is a fluorescent dye that binds to DNA. When excited by 488nm laser light, it can be detected with in the PE/Texas Red® channel with a bandpass filter 610/10. It is commonly used in evaluation of cell viability or DNA content in cell cycle analysis by flow cytometry.Product Details
- Phosphate-buffered saline, pH 7.2, containing 0.09% sodium azide.
- 0.5 mg/ml
- Storage & Handling
- The solution should be stored undiluted between 2°C and 8°C, and protect from light. Caution: This solution contains hazardous material; handle with care.
FC - Quality tested
- Recommended Usage
The suggested use of this solution for viability staining is 10 µl per million cells in 0.5 ml/test, and incubate for 15 minutes at 4 °C before analysis. For Cell Cycle analysis, please see our Propidium Iodide Cell Cycle Staining Protocol. Caution: This solution is toxigenic and mutagenic; handle with care.
- Excitation Laser
Blue Laser (488 nm)

- Why washing is not recommended post 7AAD or PI addition for viability check?
- These dyes bind in equilibrium with DNA. Therefore external dye concentration must be maintained during analysis and the dye should not be washed out.
