Fig 2. Determination of the optimal number of reference genes for an accurate normalization by geNorm.

Fig 2

The pairwise variation (Vn/Vn+1) between two sequential normalization factors determines the optimal numbers of reference genes required for normalization. Pairwise variation values below 0.15 indicate that additional reference genes will not have a significant effect and should be excluded from the normalization.
