Figure 2

Comparison of gene expression measurements illustrating the technical reproducibility of the spotted long oligonucleotide array. The upper left subplot shows technical replication between spotted arrays within print batches. The upper right subplot shows technical replication between replicated spots within arrays. The lower left subplot shows a self-self hybridisation (the sample is labelled to both Cy3 and Cy5 separately and hybridised together) illustrating the reproducibility between Cy3 and Cy5 fluorofores. Data was normalised using a lowess transformation implemented in the MIDAS software. Pearson correlation coefficients (r) are shown for each comparison and are representative (mean) of at least four independent experiments. Lines are lines of equality.
