||Mass spectrometry and Western blot validation: "...researchers measured individual protein levels in average copies per cell
under control conditions (growth for 96 h), along a 4-day time
course, in response to heat shock, DNA damage and osmotic
stress (Supplementary Table S2)."
||"For several well-characterized protein complexes, such as
the GroEL/ES chaperonin (160 multimeric complexes per
cell), DNA gyrase (50 A2B2 tetramers per cell) or ribonucleoside-
diphosphate reductase (300 copies per cell), cellular
abundances of the subunits reflect the expected complex
stoichiometries closely (Figure 4B Supplementary Figure S13)."
