Mean and coefficient of variation for the negative control probes. A) Comparative boxplots of the mean of the 162 negative control probes for each of the 40 microarrays were generated from the cyclic lowess normalized data. B) Comparative boxplots of the coefficient of variation of the 162 negative control probes for each of the 40 microarrays were generated from the cyclic lowess normalized data.
