<p>Average expression stability (M) following stepwise exclusion of the least stable gene across all the samples within an experimental set. The least stable gene is on the left, and the most stable on the right. The name <i>eIF-4a</i> in the figure stands for <i>eIF-4α. ACT</i> stands for “β-actin” and <i>TUB</i> stands for “β-tubulin”.</p
