FIG. 1.

Specific identification of pathogenic Escherichia coli. E. coli reference strains with different genotypes were examined by DNA microarrays and photopolymerization (see Materials and Methods section). Each panel demonstrates polymer formation on probes spotted on the DNA microarrays. The array layout shows the construction of the microarray. Probes targeting stx1 (dark gray), stx2 (hatched), per (white), and eae (light gray) were spotted in triplicate, and positive controls for polymer formation (black) were spotted along the edges.
