Figure 3.

Fluorescence image of a portion of a high-density oligonucleotide array containing 25-mer probes to nearly every gene on Saccharomyces cerevisiae chromosomes 5–10 after hybridization of YMR117c two-hybrid sample. The three lighted strips correspond to probes covering nucleotides 156–654 of ORF YER018c, nucleotides 1860–2484 of YER032w, and nucleotides 4092–4452 of YGL197w. Terminal probes are described as the most 5′ nucleotide of the most 5′ probe and the most 3′ nucleotide of the most 3′ probes that gave a positive signal. Dark areas correspond to probes for genes not present after genetic selection.
