Overview of I-FISH techniques

Technique Brief description Advantages Limitations Refs
I-FISH with centromeric probes I-FISH on interpahse nuclei painting pericentromeric (heterochromatic) regions High hybridization efficiency, chromosome specifity (apart few chromosomes) Signal associations, impossible to analyze chromosomes 5,13, 14, 19, 21, 22; heteromorphisms [7,10,20-22,30,35,41,58-60,81,82]

I-FISH with site-specific probes I-FISH painting specific euchromatic genomic loci Small specific genomic loci are visualized Low hybridization efficiency, numerous artifacts [8,13,28,42,47-50,69]

I-FISH with wcp I-FISH painting chromosome territories Identification of nuclear chromosome territories Chromosome territories are ambiguous, no additional information [57,70-72,93]

mFISH Multicolor I-FISH with >2 probes labeled by different fluorochromes/ligands Analysis of several targeted genomic loci Difficulty to distinguish between artifacts and aneuploidy/polyploidy [7,10,20-22,30,35]

mFISH/QFISH mFISH + QFISH digitalization of FISH signals Distinguishes between FISH artifacts and aneuploidy (polyploidy) Same as mFISH [7,10,24-29,32,35]

MFISH Simultaneous visualization of the complete set of chromosomes in an interphase nucleus All chromosome territories are simultaneously seen Exceedingly sophisticated analysis; data poorly interpretable [70,93]

ICS-MCB Chromosome-specific MCB generated on interphase nuclei Visualization of whole banded interphase chromosomes in their integrity A pair of homologous chromosomes is studied per assay; relative complexity of the analysis [7,10,13,19,23,24,26-29,31,33-35,74,75]
