[Detection of mdr1 gene by real-time fluorescence quantitative polymerase chain reaction using Taq Man-MGB probe].

ABSTRACT

OBJECTIVE: Primer Express 2.0 software was used to design the primers and the MGB probe. With the plasmid pHaMDR1/A containing mdr1 cDNA as the template, we established a real-time fluorescent quantitative polymerase chain reaction system, which, at the template concentration of 3.061 x 10(3) to 3.061 x 10(9) cps/ml, had a correlation coefficient of 0.988243 between template concentration and threshold cycle value. This PCR method allows sensitive, specific and quantitative detection of human mdr1 gene.
