Figure 1:
Inter-array replicate correlation suggests heterogeneity in single cells. Inter-array replicate correlations (minimum log2 intensity = 7) with all pair-wise comparisons of 5 replicates for each cell number group (100, 10, 1 cell) were hierarchically clustered and plotted in a heat map, with the dendrograms shown above and to the left of the group labels. High inter-array replicate correlation was observed within the 100 cell group and to a lesser extent in the single cell group.
