The change in expression with quantity of starting RNA. Depicted are "MA" plots where the difference of two log2-intensities (y-axis) is plotted against the average of the log2-intensities. Here we show the agreement of log2-intensity between a section of the 250 ng experiment and all four levels of starting RNA (using replicate array-sections to make the 250 ng vs 250 ng comparison).
