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
