Propidium iodide (or PI) is an intercalating agent and a fluorescent molecule with a molecular mass of 668.4 Da that can be used to stain cells. When excited with 488 nm wavelength light, it fluoresces red. PI binds to both DNA and RNA, so the latter must be removed by digestion with ribonucleases. The content of DNA as determined by flow cytometry, can reveal useful information about the cell cycle and the proteins involved in the regulation of the cell cycle. This reagent may be used to analyze cell cycle by flow cytometry in addition to use with antibodies for examining the expression of proteins during the cell cycle.

Storage Buffer

In PBS (pH7.2), 0.09% NaN3


Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Application

Flow cytometry

Propidium Iodide Solution can be used in evaluation of apoptosis, cell viability and cell cycle analysis by flow cytometry.      


This reagent is used to analyze cell cycle by flow cytometry. It needs not dilution. Use 5 μL /test and incubate for 5 minutes at room temperature before analysis.
