To ensure that we can replicate the effects of Rad23A and Rad23B knock-down on HCV JcR2a infection (Fig. 9A) with an untagged virus, we performed focus-forming unit (FFU) assays using the parental virus of JcR2a, Jc1, in Huh-7.5 cells (Fig. 9E). This evidence concerns the gene RAD23B and infection.
