Figure 3

A comparison of the number of genes not detected by microarray analysis from unamplified RNA or from products generated by oligo-dT and ADP amplification methods using 500 or 50 ng starting total RNA. The number of genes below a 2 fold signal/background threshold in the RNA channel was compared between amplified and unamplified gene expression signatures as a measure of the potential transcriptome data lost during amplification.
