- Histograms of total DNA content as determined by flow cytometry, nuclear DNA content as measured manually from 4', 6-diamidino-2-phenylindole (DAPI) images (manual) and nuclear DNA content as measured automatically from color-deconvolved images (auto) were fitted to a model of pre-S-phase, post-S-phase and during S-phase changes in DNA content through the cell cycle (Figure 5). The fitting parameters are summarized this table, all values are normalized to the measured pre-S-phase DNA for that data source. The standard deviation required to match the experimental error in the pre-/post-S-phase peaks is a measure of precision. The ratio of the mean of the post-S-phase to the pre-S-phase peak gives a measure of accuracy and is expected to be 2.
