Mr. Wang et al., REHYBRIDIZATION ON METAPHASES STUDIED PREVIOUSLY BY FISH - AN APPROACH TO ANALYZE CHROMOSOME-ABERRATIONS, Cancer genetics and cytogenetics, 85(1), 1995, pp. 58-60
A new protocol for fluorescence in situ rehybridization is described.
Biotin-labeled chromosome-specific DNA probes were hybridized onto met
aphases which previously had been studied by FISH. This method makes i
t possible to reexamine the same metaphase spreads with different DNA
probes. It allows for precise characterization of cytogenetic transloc
ations and for detection of multiple aberrations presented in a karyot
ype. It is especially useful in cases where a limited number of cytoge
netic preparations are available.
