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

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.
