Figure 9. Activity of HBV RNAseH inhibitors against human RNAseH1.

A. Proteins in the enriched recombinant human RNAseH1 lysates employed in the RNAseH reactions were detected by Coomassie-blue staining following SDS-PAGE. B. An oligonucleotide-directed RNAseH assay was conducted with wild-type HBV RNAseH (genotype D) and recombinant human RNAseH1 under identical reaction conditions. The inhibitory compounds were employed at 10 µM. The upper and lower panels are from the same experiment and the data were collected on a single sheet of film, so the reactions can be directly compared. DMSO, vehicle control. S, the DRF+ substrate; P1 and P2, RNAseH cleavage products.
