Propidium Iodide
Fluorochrome
Propidium Iodide (PI) is a nuclear staining agent that stains DNA. Propidium Iodide is an analogue of ethidine bromide that 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. Propidium Iodide has a fluorescence wavelength of 493/617 nm and a wavelength of 536/635 nm after Mosaic with DNA. Propidium Iodide is commonly used in the detection of apoptosis (apoptosis) or necrosis (necrosis), and is often used in flow cytometry analysis.
