Figure 2From: Identification and validation of suitable endogenous reference genes for gene expression studies in human peripheral blood Average expression calculated from the 526 Affymetrix Human 2.0 Plus microarrays for the candidate control genes selected for qRT-PCR validation. Average of the log2-transformed intensity values ± standard deviation (y-axis) is plotted for each gene. Gray columns represent the candidate control genes selected from Figure 1. White columns represent commonly used house-keeping genes and PPIB.Back to article page
