Fig. 5: 3D imaging of mitochondria of live HeLa cells with 3D-DyFI.
From: Three-dimensional random-access confocal microscopy with 3D remote focusing system

The mitochondria were labeled with mGold fluorescent protein. The left panel shows 3D live cell imaging. The right panel shows the section image in the x-y, x-z, and y-z planes. The sectioning positions are labeled in the upper right corner of the images. a, b are obtained from two different cells. The color indicates fluorescence intensity.
