Abstract:
One-step reverse transcriptase polymerase chain reaction (RT-PCR) coupled with microchip electrophoresis (MCE) was established to analyze BCR-ABL fusion gene. The use of one-step RT-PCR could simplify the RT-PCR procedure and thus reduced the risk of contamination and sample consumption. This method also enhanced the sensitivity for amplified target DNA and dramatically shorted the analysis time. Moreover, this assay can simultaneously identify b2a2 and b3a2. Orthogonal array design, which can investigated mutual effects of PCR parameters, was used to optimize the reaction system. This approach was highly effective, reproducible and sensitive, and would be suitable for the determination of BCR-ABL in clinic diagnosis.
