Multicolor fluorescence in situ hybridization (FISH) applied to FISH-banding.
During the last decade not only multicolor fluorescence in situ hybridization (FISH) using whole chromosome paints as probes, but also numerous chromosome banding techniques based on FISH have been developed for the human and for the murine genome. This review focuses on such FISH-banding techniques, which were recently defined as 'any kind of FISH technique, which provide the possibility to characterize simultaneously several chromosomal subregions smaller than a chromosome arm. FISH-banding methods fitting that definition may have quite different characteristics, but share the ability to produce a DNA-specific chromosomal banding'. While the standard chromosome banding techniques like GTG lead to a protein-related black and white banding pattern, FISH-banding techniques are DNA-specific, more colorful and, thus, more informative. For some, even high-resolution FISH-banding techniques the development is complete and they can be used for whole genome hybridizations in one step. Other FISH-banding methods are only available for selected chromosomes and/or are still under development. FISH-banding methods have successfully been applied in research in evolution- and radiation-biology, as well as in studies on the nuclear architecture. Moreover, their suitability for diagnostic purposes has been proven in prenatal, postnatal and tumor cytogenetics, indicating that they are an important tool with the potential to partly replace the conventional banding techniques in the future.
