Fig. 4. Comparison of the distribution of Bax and Cyt c in the same apoptotic cells. (A-H) Distribution of GFP-Bax (A-D) and endogenous Cyt c (E-H) within the same HeLa cells undergoing UV-induced apoptosis. (I-P) Distribution of endogenous Bax (I-L) and endogenous Cyt c (M-P) within the same apoptotic HeLa cells. The distribution of endogenous Bax and Cyt c was visualized by immunostaining. The arrowheads indicate cells in which Bax forms small complexes. Scale bars: 10 µm.
