The B. subtilis control cocktail contained equal proportions (wt/wt) of each RNA species and was spiked into cDNA reactions at 125 pg/2 ug mRNA in order to normalize Cy3 and Cy5 signals after scanning.
In subsequent samples, two-fold serial dilutions of this spiked total RNA into fresh total RNA generated a dilution series consisting of ten concentrations of each transcript for a final range of 1:100,000 to 1:51,200,000 (10 microM to 20 nM).
We plotted the signal intensity as a function of the spiked transcript concentration for oligodeoxyribonucleotide probes on the array that were complementary to these control transcripts.
As the absolute levels of these four transcripts in rat heart and brain are not known with certainty, we repeated these experiments with known concentrations of synthetic Arabidopsis cRNA that were differentially spiked into rat heart and brain RNA.
