Product Introduction
Propidium iodide (PI) is a membrane-impermeant, red fluorescent dye that stains DNA. It is generally excluded from viable cells and can penetrate damaged cells, therefore it is commonly used to identify the viability of cells. PI is suitable for fluorescence microscopy and flow cytometry.
