Macrophage Autophagy and Oxidative Stress: An Ultrastructural and Immunoelectron Microscopical Study

Figure 5

Immunoelectron microscopy of beclin-1 in AAPH-treated macrophages. Gold particles specifically localize to autophagic vesicles. Label occurs predominantly over the enveloping membranes ((a) ×31500; (b) ×31500). N: nucleus; AV: autophagic vesicle; asterisks indicate RER.
