Estimated mean values and standard deviation are displayed. For proteins (stably) bound per megabase DNA, propagated standard deviation of mean nuclear protein numbers and mean FRAP bound fractions is provided. Calculations of per-megabase-DNA counts are based on the 7.9 Gb HeLa Kyoto genome reported by Landry et al. (2013).
