Figure 2. HL-60 cells were treated with a drug, then stained with FLICA® FAM-VAD-FMK poly-caspase inhibitor reagent (green) (Cat. 92) and propidium iodide (red) (PI). Scanning laser cytometer analysis. Four populations of cells were detected: (A) Unstained live cells, (B) red necrotic cells (PI), (C) green and red late apoptotic cells (FAM-FLICA® plus PI), and (D) green early apoptotic cells (FAM-FLICA®).

Figure 3. Cell death in primary rat hippocampal neurons. (D) is a composite of FLICA® FAM-DEVD-FMK (B), PI (C), and Hoechst (A). DNA is labeled in 4 cells (A), 3 cells are caspase-positive (B), 2 are membrane-compromised (C). One cell is in early apoptosis (green but not red). Two FLICA®-positive cells are also PI-positive (red, C) (becoming membrane compromised) and are in the late stages of apoptosis rather than necrosis. Data courtesy of Dr. Z.
