Preferred Label : Fluorescence In Situ Hybridization;
NCIt related terms : FISH;
CISMeF acronym : FISH;
NCIt definition : A physical mapping approach that uses fluorescent tags to detect hybridization of
probes within metaphase chromosomes or less condensed somatic interphase chromatin.
This technique can be used for identification of chromosomal abnormalities and for
gene mapping.;
Alternative definition : NCI-GLOSS: A laboratory technique used to look at genes or chromosomes in cells and
tissues. Pieces of DNA that contain a fluorescent dye are made in the laboratory and
added to cells or tissues on a glass slide. When these pieces of DNA bind to specific
genes or areas of chromosomes on the slide, they light up when viewed under a microscope
with a special light.;
