PGSM potentiates colony suppression in replicon cells in combination with IFN-α and DAAs. HCV replicon cells were treated with various concentrations of PGSM and IFN-α, PGSM and BMS-790052 (NS5Ai), and PGSM and VX-950 (PI) as indicated. Three weeks after treatment, remaining surviving cells were stained with crystal violet.
