Fluorescence In Situ Hybridisation (FISH) is a targeted technique, described as a’ hybrid’ of molecular genetic and conventional cytogenetic technologies. FISH can be applied to both cultured and uncultured cells unlike standard cytogenetic techniques which require actively-dividing cells. This means that a variety of specimen types can be processed successfully, even those that conventionally don’t grow well in culture, making FISH a powerful tool for the study of acquired abnormality in bone marrows, tumours and paraffin-embedded specimens.
FISH can determine the copy number of a region of interest and detect specific chromosome and/or and gene rearrangements involving that locus. As a complementary technique, or as a test for targeted abnormalities, FISH has expanded our capabilities for more accurate, rapid and refined cytogenetic diagnoses.
FISH using BCR and ABL1 specific probes detects the t(9;22)(q34;q11.2) Philadelphia chromosome rearrangement.

Fluorescently-labelled DNA probes specific to a gene or region of interest are applied and hybridised to standard cytogenetic preparations on glass slides. Probe signals are visualised on nuclei or chromosomes 'in situ' by fluorescent microscopy.
