Figure 3From: ReadqPCR and NormqPCR: R packages for the reading, quality checking and normalisation of RT-qPCR quantification cycle (Cq) dataqPCRdDCq.png. Relative (log2) fold change between case and control for a number of genes. Blue bars show mean, error bars ± 1 standard deviation Red bars show instances where the presence of the transcript has been detected in the one condition, but not in the other, and as such no fold change or standard deviation (of fold change) can be calculated.Back to article page
