Figure 2From: DNA Polymerases as targets for gene therapy of hepatocellular carcinomaRelative expression level of AFP in three cell lines. AFP and β - actin mRNA levels of HCC cells HepG2, Hep3B and normal liver cell HL7702 were quantified by fluorescent real time quantitative PCR. β-Actin was used as the internal control to calculate the relative mRNA level of AFP.Back to article page
