Microarray Scanner:The two Cy-labeled cDNA samples are mixed and hybridized to a single microarray that is then scanned in a microarray scanner to visualize fluorescence of the two fluorophores after excitation with a laser beam of a defined wavelength.

Array Scanner:In array analysis, a nucleic acid-containing sample is labeled and then … with a streptavidin-phycoerythrin conjugate and visualized with an array scanner.
