Fig 1. Selection of the most suitable reference genes for 0h and 6h PMI in the hippocampus of Naïve rats.

Fig 1

Expression stability measurements for the 5 reference genes calculated by geNorm (A) and NormFinder (B). The x-axis from left to right indicates the ranking of the genes according to their expression stability; lower values indicate higher expression stability. C) Determination of the optimal number of reference genes for normalization by geNorm. The Software calculates the normalization factor from at least two genes at which the variable V defines the pair-wise variation between two sequential normalization factors.
