Figure 3From: Selecting control genes for RT-QPCR using public microarray dataScatter plots of standard deviation versus mean log-intensity for two validation data sets (from left to right: NKI and UPP). The top 100 breast cancer control genes resulting from aggregating eight data sets are plotted as circles. Triangles correspond to the five control genes used in [17] (NKI does not contain the ACTB gene).Back to article page
