Proportion of PlasTi-microarray probes with SNR ≥ 3 in CSH-based microarray experiments. Graphs present percentages of probes with SNR ≥ 3 in CSH-based microarray experiments, separately for "coding" (panels A, C, E) and "non-coding" probes (panels B, D, F). Each bar represents the value obtained from one channel of one microarray. Only probes with both replicate spots flagged as good were considered, and the SNR values were averaged between the replicates. a-f - arrays, as indicated in (Table 5). M -probes matching analyzed genome sequence with E ≤ 10-3, NM - probes not matching the genome sequence with E ≤ 10-3. Colors represent array channels: green - Cy3 channel, red - Cy5 channel.
