Propidium Iodide Staining Solution (1mg/ml) in water

(HB0821)
Technical documents: SDS Datasheet

Product overview

Name Propidium Iodide Staining Solution (1mg/ml) in water
Alternative names PI
Biological description

Propidium iodide (PI) is a widely used red-fluorescent intercalating agent that binds and labels nucleic acids. This is a 1mg/ml staining solution.


Propidium iodide is membrane impermeant and is therefore frequently used to selectively identify dead cells and is commonly used in flow cytometry to evaluate cell viability.


Propidium iodide (PI) is often used in flow cytometry, fluorescent microscopy and confocal laser scanning microscopy applications.

Frequently used with Oxazole Yellow (YP1) when staining for apoptotic and necrotic cells as apoptotic cells remain impermeant to propidium iodide but permeable to Oxazole Yellow (YP1).

 

Once bound to the nucleic acids, its fluorescence is enhanced 20- to 30-fold. Wavelength Maxima: Excitation ~535nm, Emission ~617nm

Description

Red-fluorescent cell viability stain. 1mg/ml staining solution in water.

Propidium lodide is a membrane-impermeable DNA binding dye used to label cell nuclei in immunofluorescence experiments. Propidium lodide from Hello Bio labels cell nuclei (red) at 1 µg/ml when co-stained with a anti- vimentin antibody (green). For protocol see #Protocol 1 in application notes below.

Application notes

#Protocol 1: Propidium Iodide counterstaining of HEK293T cells

  • HEK293T cells were cultured on coverslips in 10% FBS in DMEM and fixed with 4% PFA. Immunocytochemistry was performed following our ICC protocol using an anti-vimentin monoclonal antibody at 1µg/ml.
  • Prodidium iodide working solution was prepared consisting of 1µg/ml Propidium Iodide and 10µg/ml RNase A and incubated with cells for 30 minutes at room temperature.
  • Following washing with PBS, coverslips were mounted and imaged using a confocal microscope using either a 532nm or 514nm laser for excitation
