Activity of cLF, N-lobe and C-lobe against HCV entry into Huh 7.5 cells by. (A) HCV particles were pre-incubated with purified proteins prior to infection (neutralization). (B) Huh 7.5 cells were treated with purified proteins prior to infection with HCV (protection). Lane 1, DNA ladder; lane 2, negative control; lane 3, positive control. Lane 4-9, Proteins at different concentrations, as indicated under the gel graph. The upper arrow pointed the Rulc which served as internal control, while the lower arrow pointed the positive amplified 174 bp of HCV.
