With semi quantitative noncompetitive RT-PCR assay, the hTERT mRNA expression in IMR90 cells was negative and the normalized hTERT mRNA expression in T24 cells was 0.06[hTERT(IOD)/GAPDH(IOD)].

• 半定量非竞争RT-PCR检测IMR90和T24细胞株hTERT mRNA的表达，IMR90细胞株hTERT mRNA无表达，T24细胞株hTERT mRNA表达为0.；06[hTERT(IOD)/GAPDH(IOD)]。
