- Overview
  - Propidium iodide (PI) is an ethidium bromide analog that emits red fluorescence upon intercalation with double-stranded DNA. PI does not permeate viable cell membranes, but passes through disturbed cell membranes and stains the nuclei. PI is often used in combination with a fluorescein compound, such as Calcein-AM or FDA, for simultaneous staining of viable and dead cells. The excitation and emission wavelengths of PI-DNA complex are 535 nm and 615 nm, respectively.

  - Application Description
    
    Staining Procedure
    1.Prepare 10-50 μM PI solution with PBS or an appropriate buffer.a)
    2.Add PI solution with 1/10 of the volume of cell culture medium to the cell culture.b)
    3.Incubate the cell at 37°C for 10-20 min.
    4.Wash cells twice with PBS or an appropriate buffer.
    5.Observe the cells under a fluorescence microscope with 535 nm excitation and 615 nm emission filters.
    a) Since PI may be carcinogenic, extreme care is necessary during handling.
    b) Or you may replace the culture medium with 1/10 concentration of PI buffer solution.
