Fig. 2

PCA of technical and biological replicates for each time point. Each hue corresponds to a different time-point. Each time-point has two biological replicates which are represented in different tints. Technical replicates are represented with exactly the same hue and tint. Technical noise is small. Most variation occurs between time-points 0 W and 2 W. No unexpected batch effects take place, other than the controlled experimental factors
