Figure 3From: Selection and reliability of internal reference genes for quantitative PCR verification of transcriptomics during the differentiation process of porcine adult mesenchymal stem cellsMost-stable genes by geNorm and calculation of the optimal number of internal control genes. (a) geNorm results for the average expression ratio stability (M) of potential internal-control genes calculated by pairwise comparison. (b) determination of the optimal internal-control genes number for normalization (lowest M).Back to article page
