Reproducibility of expression levels. Full absolute quantification analyses were completed for cell lysates from duplicate parallel turbidostat cultures prepared at two independent sites: Cambridge (termed C1 and C2) and Manchester (termed M1 and M2). For each protein, absolute quantification was expressed as molecules/cell where n = 3 technical replicates (digest + MS analyses); the error bars are the S.E. of these analyses. The shaded area highlights the 95% confidence limits of the quantification comparisons.
