Fig. 3: Responses of different arrays within the same cell are not strongly correlated.

Upper plots: The response of one array to a given ligand is plotted against the response of another array within the same cell to the same ligand. To account for the overall shift in the response distribution, each value was shifted by the mean and normalized by the standard deviation of the respective dataset. Data are shown for responses to serine and aspartate in cells from both the exponential (left) and stationary (right) growth phases (~100 arrays in each case). The corresponding two-sided Spearman correlation values (left to right) are: 0.2 (p = 0.04), 0.13 (p = 0.18), 0.04 (p = 0.65), and 0.13 (p = 0.12). Lower plots: Distributions of the pairwise 2D distances (d, see text) between responses of arrays within the same cell. Data are shown for actual array pairs (gray bars) and for randomly paired arrays from the general population (green bars).
