Stepwise exclusion and pair-wise variation (v) analysis by GeNorm. (A) Stepwise exclusion analysis in which the least stable (highest M value) gene is excluded sequentially (from left to right) until the most stable pair of genes remains. (B) Pair-wise variation analysis showing the normalization factor (NF) variability (V) that results from including an additional gene to the NF calculation. A V increase corresponds to a decrease in NF reliability.
