Deconvolution results for imaging of live cells expressing histone H2B fused to mClover to visualize chromosome conformation. (a) A focal stack (512 × 512 × 128 voxels) of the cell was captured over a span of one and a half hours with a time interval between focal stacks of three minutes. The 49-th z slice of the measurement, the deconvolved volume using our method, and the deconvolved volume using the Richardson-Lucy algorithm (100 iterations) is shown, with the time interval of fifteen minutes between frames along each row. (b) A second focal stack (512 × 512 × 100 voxels) shows a cell recorded for one hour with a time interval of three minutes. The 37-th z slice is shown, and the time interval between frames in each row is fifteen minutes. The corresponding deconvolved images are visualized in the second and third rows, respectively. The scale bar has the length of 10 μm. 3D volume renderings of these cells are provided as Supplementary Videos 3 and 4.
