Figure 4From: ReadqPCR and NormqPCR: R packages for the reading, quality checking and normalisation of RT-qPCR quantification cycle (Cq) dataqPCRplotByRef.png. These show the mean ΔCq values for all values following normalisation by a reference gene, in each case ordered by differing reference genes. In this case B2m appears to show the least correlation with the others, suggesting it might be removed when calculating the normalisation factor.Back to article page
