    FISH (Fluorescence in situ hybridization)
    Fluorescence in situ hybridization
    Hybridizes with the target DNA using a probe labeled with a fluorescent dye, and uses the fluorescent site that develops at a specific wavelength as a signal on the chromosome. How to detect under fluorescence microscope.
    There is a direct method in which a probe labeled with a fluorescent dye is directly bound to the target DNA, and an indirect method in which the probe labeled with a labeling substance is bound to the target DNA, and then the labeled probe and fluorescent substance are bound to develop color. .
