Figure 4.

Scatterplot 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.
