From: Genomic selection of reference genes for real-time PCR in human myocardium
Average expression variability of reference genes (M), during stepwise exclusion of the least stable gene. At each step the most variable gene (highest M-value) is excluded and M is recalculated. This process continues in a step-wise manner until the two most stable genes remain. The figure indicates that GAPDH is least stably expressed relative to the other genes, and that SRP14 and TPT1 have the most stable expression.
