 To construct and evaluate the competitive quantitative RT-PCR method for detecting the fusion gene of AML1-ETO in the patients of t(8;21)AML(acute myeloid leukemia).     ///    "the sensitive competitive RT-PCR method is developed, which allows the quantitation of the number of AML1-ETO transcriptions in t(8;21)AML patients at different phases. "    ///    t(8;21) AML patients in different survival conditions express AML1-ETO gene quite differently..     ///    "The authors used the method of splicing by overlapping extension (SOE) to obtain the competitive DNA fragment, with which they set up the competitive quantitative RT-PCR assay to detect AML1-ETO chimeric genes in the patients of t(8;21) AML.
