Microarray schematics. a Probes corresponding to the characteristic fragments of a given gene are placed in different locations across the array; b Single probes are arranged in sets corresponding to the same region of the gene. DNA that hybridizes to the probe can be detected using a fluorescent reporter system. Increasing the number of probes to which cDNA hybridizes correctly, increases the contrast between this probe set (probe set A) and any other probe set (probe set B)
