Description

General description

PI is used for selective labelling of dead cells.

Propidium iodide is a fluorescent intercalating agent used for staining. It functions as an apoptosis marker and has linear DNA-binding capacity. Propidium iodide is an effective indicator of tissue injury.

Application

Propidium iodide has been used:

• to stain DNA in cell cycle analysis
• to stain cells and cell nuclei
• for the preparation of propidium iodide (PI)stock solution
• to stain cells for flow cytometry

in scrape-loading dye transfer assay
