Widefield confocal imaging provides the resolution, sensitivity, dynamic range, and background fluorescence rejection for fluorescence imaging of genetic and protein microarrays. The same instruments can also be adapted for imaging tissue arrays, both in brightfield and in fluorescence. We have reviewed the principles of confocal microscopy and the MACROscope® technology on which the DNAscope™ is based. Images of DNA and tissue microarrays were shown, and the steps required to image and analyze a genetic microarray were described.
