Fig. 3From: Evaluation of the anti-cancer potential of Cedrus deodara total lignans by inducing apoptosis of A549 cellsApoptosis of CTL treatment in A549 cells. The A549 cells were treated with varying concentrations of CTL (a-e: 0, 10, 20, 30 and 40 μg/mL) for 48 h. Then, the A549 cells were stained with propidium iodide (PI) and Annexin V-FITC as described in Methods. The stained A549 cells were analyzed for apoptosis by using a FACS Calibur flow cytometryBack to article page
