Average expression consistency of control genes in qRT-PCR.

<p>Average expression consistency (M) was calculated with the GeNorm algorithm <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0072884#pone.0072884-Vandesompele1" target="_blank">[18]</a> based on qRT-PCR for the indicated control gene on a panel of 14 leukemia samples and one cord blood sample. Lower M values relate to genes which proved to have more consistent expression levels across the samples used.
