Figure 7From: Selection of reference genes for gene expression studies in ultraviolet B-irradiated human skin fibroblasts using quantitative real-time PCRThe stepwise exclusion of least stable genes by calculating the average M value. The average value of the expression stability M for each gene was determined using geNorm software. Genes on the x-axis are ordered from the left to the right according to their expression stability from the least to the most stable.Back to article page
