Figure 5From: The inhibition of the mammalian DNA methyltransferase 3a (Dnmt3a) by dietary black tea and coffee polyphenolsMeasurement of IC50 values for compounds N6, N7, N8 and N12. For compounds N6, N7, N8 and N11 DNA methylation kinetics were carried out at different concentration of the compounds to determine the IC50 value. The error bars show the maximal deviations in repeated experiments. IC50 values are valid by ±30%.Back to article page
