FIG. 1.

(A) Microarray print pattern. The number after the probe name represents the approximate position of the complementary target region, utilizing G. chapellei or D. desulfuricans 16S rRNA numbering. Open circles indicate the print locations of buffer blanks, which were used to assess capture probe carryover during the printing process. (B) Secondary-structure diagrams for G. chapellei and D. desulfuricans capture probes, based on the D. desulfuricans (accession number M34113) model of Guttell (26). Lines next to the diagrams indicate the positions of the capture probes.
