FIG. 2.
Analysis of Fas-induced apoptosis. Jurkat and B5 uninduced and induced cells were treated for 6 h with anti-human Fas antibody DX2 (2 μg/ml), and protein G (2 μg/ml) to induce apoptosis. Cells were stained with annexin V-FITC and propidium iodide and analyzed by flow cytometry. The results are averages of three independent experiments.
