Figure 4From: Optimization and evaluation of T7 based RNA linear amplification protocols for cDNA microarray analysisScatterplot of the t-statistics (the numerical score underlying a t -test) comparing the differences in gene expression between amplified and unamplified RNA for BC2 (X-axis) and BC91 (Y-axis). The tests were based on 7 amplified total RNA and 5 unamplified poly(A)+ RNA samples for BC2, and 2 amplified total RNA and 4 unamplified poly(A)+ RNA samples for BC91.Back to article page
