Figure 4.

Hybridization pattern for region B of the P.aeruginosa 16S rRNA gene. Each probe was spotted in duplicate onto the glass slide. The pattern of fluorescence is shown on the left and a color-coded representation of the results is shown on the right. Red-filled circles represent strong experimental hybridization signals (average pixel intensity 10 000–50 000). Gray-filled circles represent weak experimental hybridization signals (average pixel intensity <10 000). Open circles represent absence of detectable hybridization signal (average pixel intensity <1000). Solid rectangular outlines represent positions of predicted hybridization based on the existence of a single perfect match within the target.
