RT-QPCR experiment. Standard deviation as a function of the mean expression level (expressed as raw Ct values) of 47 genes in a RT-QPCR experiment. Higher expression levels correspond to smaller raw Ct values. Control genes are represented by triangles, test genes by circles. The new control genes RPS11 and UBB are in the lower left corner.
