From: An evaluation of potential reference genes for stability of expression in two salmonid cell lines after infection with either Piscirickettsia salmonis or IPNV

Figure 4

Programmed analysis of expression stability of the five putative reference genes. (a) Average expression stability values (M) of the potential reference genes after stepwise exclusion of the least stable gene calculated by the statistical software geNorm, plotted from least stable (left) to most stable (right). (b) Pairwise variation analysis between the normalization factors NFn and NFn+1, to determine the optimal number of control genes for normalisation. A and B, P. salmonis infection experiment, C and D, IPNV infection experiment.
