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

- 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.

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