Figure 2From: Selection of reliable reference genes for quantitative real-time PCR in human T cells and neutrophilsDetermination of the optimal number of reference genes using geNorm. Pair-wise variation (Vn/n+1) analysis between the normalization factors NFn and NFn+1 to determine the number of control genes required for normalization was performed (arrowhead indicates optimal number). For ranking order of candidate reference genes see Table 3, geNorm ranking.Back to article page
