Fig. 2
Super-resolution 3D imaging of chromosome regions. a Widefield 3D image of a single fluorescently labeled chromatin region (maximum intensity projection of a z-stack). b,c Super-resolution 3D images of the same structure obtained with ZOLA-3D [35]. b A color-coded view, where color indicates axial coordinate. c Two 500-nm-thick slices through the 3D super-resolution image are shown, with two 1āĪ¼māĆā1āĪ¼m regions (yellow boxes) shown magnified to the right. The white arrow points to an isolated piece of chromatin fiber. For an animated 3D view, see Additional fileĀ 2: Video S1
