Introduction

Propidium iodide is a laboratory reagent for the fluorescent staining of nucleic acids. Useful for flow cytometry for staining apoptotic cells and nuclei. Because it is membrane impermeable the state of the cell determines the ability of propidium iodide from staining viable and apoptotic cells. Propidium iodide has been used in in combination with Hoechst fluorescent stain (sc-202503) to observe cell viability via fluorescent microscopy. Propidium iodide is excitable at 536 nm and Emits at 617 nm (red).
