Direct comparison activators by synthesizing sets of mixed base 25-mers on a single microarray surface. Each oligonucleotide set was synthesized using a different activator. To avoid order-of-synthesis effects, all sets were synthesized approximately in parallel using the scheme shown in A. The results for Activator 42, DCI and ETT  (Graph B) were evaluated using the intensity values obtained by hybridizing with a Cy3-labeled complementary oligonucleotide
