FAQ

What is the primary use of propidium iodide?

Propidium iodide is primarily used as a nuclear counterstain in fluorescence microscopy, helping identify dead cells in various assays.

Can propidium iodide be used in live cell imaging?

No, propidium iodide cannot be used for live cell imaging since it can only penetrate dead or damaged cells.

How does propidium iodide compare to other fluorescent dyes?

Unlike many other fluorescent dyes, propidium iodide is specific for nucleic acids and provides a distinct orange fluorescence, commonly used in conjunction with other dyes for multi-staining applications.
