Apoptosis in MWCNT-exposed BECs was measured at day 5 by flow cytometry using annexin V-FITC staining with a propidium iodide counterstain. MWCNT treatments of 3 μg/ml or less were not found to elevate annexin-positive cells or PI-permeable cells, indicating that apoptosis was not significantly induced by these treatments by day 5.
