Staining Nucleic Acids with Propidium Iodide



Staining Nucleic Acids with Propidium Iodide

Propidium iodide (Molecular Probes, Eugene, OR) is a membrane-impermeant dye
that stains by intercalating into nucleic acid molecules. It binds both DNA and RNA. (David K. Hanzel and Siobhan C. Pickett, Molecular Dynamics)

Does the propidium iodide diluted in water become inactive? What is validity time of propidium iodide solution stored at 4oC?

Thank you
