Propidium Iodide (PI) binds to double-stranded DNA. PI cannot cross intact plasma membrane and therefore will only be present in DNA of cells where the plasma membrane has been compromised/ permeabilized.
For Microscopy analysis: PI can be viewed using rhodamine(red) filter (?= 536/617). Cells will only be stained if the membrane has been permeated, either naturally (non-viable cells) or with detergents (for fluorescent staining).
Flow Cytometry analysis: PI staining can be monitored in FL2 (DNA content) or FL3 (viability) channel.
