Fluorescence-activated cell sorting (FACS) analysis of apoptosis in human Muller (MIO-M1) cells incubated with Nε-(3-formyl-3,4-dehydropiperidino)lysine (FDP-lysine) human serum albumin (HSA) measured using fluorescein isothiocyanate (FITC)-labeled annexin V and PI. A: Representative scatter plots showing the distribution of annexin V and PI staining for control and FDP-lysine-HSA-treated MIO-M1 cells. Cells are classified as “viable” (bottom left), “apoptotic” (bottom right), or “necrotic” (top left and right). Cells exposed to 0.5 mg/ml FDP-lysine HSA showed a distinct shift into the bottom right quadrant, consistent with apoptosis (B). Quantitative analysis of the percentage of viable, apoptotic, or necrotic cells by FACS analysis. *** p<0.001 versus untreated cells.
