Propidium Iodide (PI) is a ready-to-use band-aid for the exclusion of abstract beef in breeze cytometric analysis. PI binds to bifold abandoned DNA by intercalating amid basepairs, but is excluded from beef with complete claret membranes. PI can be acclimated in FL3 for inviability exclusion, but should be analyzed in FL2 if acclimated as a counterstain for FITC Annexin V.
