Figure 2From: Accurate normalization of real-time quantitative RT-PCR data by geometric averaging of multiple internal control genesAverage expression stability values (M) of remaining control genes during stepwise exclusion of the least stable control gene in the different tissue panels (black circle, neuroblastoma; white circle, normal pool; white square, bone marrow; black square, leukocyte; gray circle, fibroblast; gray square, systematic error). See also Table 3 for the ranking of the genes according to their expression stability.Back to article page
