Description

General description

Propidium iodide (PI) is a fluorescent dye thatcan be used for staining nucleic acids. It is impermeable in viable orintact cells. It can penetrate easily into dead, dying, or membrane-compromisedcells. PI has the capacity to bind easily to DNA.

Application

Propidiumiodide has been used: to detect cell cycle by flow cytometry and γH2AXand pH3 analysis,apoptosis assay in hepatic stellate cells (HSCs), in stainingbuffer/solution to stain the cells for cell cycle analysis
