Figure 1From: Intensity-based analysis of dual-color gene expression data as an alternative to ratio-based analysis to enhance reproducibilityIntensities of the same sample measured on separate arrays are highly correlated. Hierarchical clustering of log2-transformed single channel intensities of the complete cell line experiment. Only genes with an average intensity A > 7 were used. Note that identical cell line-treatment combinations always cluster together, regardless of the co-hybridized sample. Sample naming = [cell line] [treatment] [duplicate set].Back to article page
