Figure 1From: Validation of putative reference genes for gene expression studies in human hepatocellular carcinoma using real-time quantitative RT-PCR QRT-PCR inhibitor detection in all samples. ΔCt for amplification of alien RNA in samples of 100 ng and 20 ng RNA respectively were compared with that of Alien RNA alone. Each sample was spiked with 105 copies of alien RNA transcripts.Back to article page
