Description
Product Description
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.
Chemical Structure
Technical info
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 37oC 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 replac
e the culture medium with 1/10 concentration of PI buffer solution.
