Propidium Iodide, 1 mg/mL solution in water, CAS 25535-16-4

Description: Propidium iodide (PI) is a cell impermeable nucleic acid intercalating dye. Because PI is excluded from viable cells it can be used in apoptotic studies to distinguish necrotic cells or cells in the late stages of apoptosis from viable cells or cells in early apoptosis where cell membranes are still intact. PI is also utilized as a counterstain in multicolor fluorescent imaging. After entering cells and binding to DNA and RNA, the fluorescence of PI is enhanced 20- to 30-fold. PI can be used in flow cytometry and fluorescence microscopy.
