Fluorescence in situ hybridization (FISH) from lymphocytes was analyzed by confocal laser microscopy imaging. Representative chromosomes counterstained with DAPI (blue) and Y chromosome-specific probe conjugated with FITC (fluorescein isothiocyanate, in green) fluorescence images, their superimposition (merged image), and a transmitted light DIC (differential interference contrast) image (gray) are shown.
