Description and Uses
Propidium iodide (PI) is membrane impermeant and generally excluded from viable cells. However, it can easily penetrate dead or damaged cells and as such is commonly used for identifying cell viability in a population or as a counterstain in multicolor fluorescent techniques. It binds to DNA and RNA by intercalating between the bases. PI is excited at 488-
Used as fluorescent stain for nucleic acids,and used in flow cytometry to evaluate cell viability
