FIG. 1.

Comparison matrix of normalized intensity values from microarray slides by scatter plot. Normalized logarithmic intensity values obtained from each individual array were compared between each sample and depicted as a scatter plot. The annotation of the x axis is shown to the right of the matrix, whereas the y axis annotation is shown on top. Values that differ more than 1.8-fold are shown in red (high) or green (low). Also shown is the correlation coefficient r² for each comparison. The highest correlation was observed when for results obtained from the same sample hybridized to two arrays. Comparisons between the two different infected samples, I-8 versus I-9, were more similar to each other than comparisons between infected samples and mock-infected DMVEC isolated in parallel.
