||"In the present study, [researchers] demonstrate that the protein copy numbers of a human cell span at least seven orders of magnitude. This range is similar to that determined in mouse cells (Schwanhausser et al, 2011). This finding is furthermore in good agreement with the volume of the relevant cell types, namely ~0.2µm^3 in L. interrogans (Beck et al, 2009), and about ~30µm^3 in S. cerevisiae and ~4000µm^3 in U2OS, (assuming spherical shape and 4 and 20µm diameter for yeast and U2OS, respectively)."
