 The persistence of the AML1-ETO rearrangement performed by reverse transcription polymerase chain reaction (RT-PCR) has been reported in acute myeloid leukemia (AML) patients in long-term complete remission (CR).     ///    "Here, we present a new quantitative real-time PCR method to detect AML1-ETO rearrangement using fluorescently labeled probes. "    ///    Quantitative detection of AML1-ETO rearrangement by real-time RT-PCR using fluorescently labeled probes..     ///    Quantitative detection of AML1-ETO was performed in capillary tubes using two fluorescently labeled probes in the LightCycler equipment.     ///    The inter-assay coefficient of variation was 19% for AML1-ETO and 12% for AML.     ///    "The intra-assay coefficient of variation was 4% for AML1-ETO, and 7% for AML. "    ///    The regression coefficients obtained for standard curves of AML1-ETO and AML were all greater than 0.98.     ///    A log reduction from two to four in the AML1-ETO/AML ratio was evident after CR.
