WebAug 30, 2004 · Live cells, being exclusive of PI, will stain SYTO9 positive and fluoresce in green. It should be noted that, although the membrane impermeability of PI is claimed by the manufacturer to be the major reason for nonstaining of vital cells, some strains are said to possess efflux pumps that can actively remove PI from the cell. ... WebMar 24, 2024 · When inspecting the dot plots of the SYTO 9 and PI staining, a bacterial sub-population of SYTO 9 low PI high could be discerned, which reached 16.37% and 52.47% for bacteria treated with 25 and 50 µg/mL AEA, respectively (Figure 6F). This suggests increased membrane leakage and membrane permeability at these AEA concentrations.
