Objective: To establish a rapid and convenient method of multi-color fluorescence in situ hybridization (FISH) on several different tissue samples: peripheral blood samples, amniotic fluid, embryos and bone marrow samples.
Methods: FISH analysis was carried out on different tissue samples, using probes specific for chromosomes 13,18,21,X and Y or for BCR/ABL gene.
Results: FISH analysis could reveal hybridization signals on metaphase chromosomes and interphase nuclei, it is also possible to detect chromosome aberrations.
Conclusion: Multi-color FISH is clinically useful tool, which can be used as an adjunct to conventional chromosome analysis for prenatal diagnosis , preimplantation genetic diagnosis and diagnosis of leukemia.
