Propidium Iodide (PI) is a nuclear staining agent that stains DNA. It is an analogue of ethidine bromide, which emits red fluorescence upon embedding in double-stranded DNA. Propidium Iodide cannot pass through living cell membranes, but it can pass through damaged cell membranes to stain the nucleus. It is commonly used in the detection of apoptosis or necrosis, and is often used in flow cytometry analysis.
