Figure 10From: Effect of RNA quality on transcript intensity levels in microarray analysis of human post-mortem brain tissuesConsistency of chip RNA quality for two chip hybridizations. Scatter plot of the beta actin ratios of paired samples hybridized to two Affymetrix chip platforms (a mixture of brain tissues). Line shows the linear trend (r = 0.6) calculated on the basis of data points in the interval 0.3 – 1 of HG-U133_AB beta actin ratio.Back to article page
