(A–C) Double immunolabeling of calpain-2 (red) and actin (phalloidin, green) in a differentiated PC12 cell. Calpain-2 (B) localizes almost exclusively to the varicosity contained in the varicone (A). In a Z-projection across the varicone (C), actin staining is detected around the varicosity, while calpain-2 fills the space within. Scale bar = 10 µm.
