Figure 3From: Microarray analysis of defined Mycobacterium tuberculosis populations using RNA amplification strategiesA 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.Back to article page
