Figure 1From: Effect of RNA quality on transcript intensity levels in microarray analysis of human post-mortem brain tissuesMeasures of RNA quality of Affymetrix GeneChip. Measures of RNA quality of Affymetrix GeneChip by the example of Dataset 1: a) 5'/3' beta actin ratio vs 5'/3' GAPDH ratio; b) 5'/3' beta actin ratio vs RNA QC index; c) beta actin 5'-end abundance vs RNA QC index.Back to article page
