FISH using ICRF
RARα 121 cosmid probe in the t(5;17) cases. (A) Case 54: translocation of RARα sequences (green) to the der(5), identified using a chromosome 5q31 Oncor probe (red) using DAPI banding. (B) Case 55: RARα signals (green) were detected only on the normal chromosome 17. R banding using propidium iodide does not permit capture of double minute chromosomes.
