(A) Quantification of HCV core protein and HCV RNA in fractions from sucrose density gradient centrifugation of the patient sera. (B) Western blot analysis of HCV native core protein in HCV-infected-patient sera or HCV-negative sera. Lanes 1 and 2, HCV core protein in RK13 cells harvested 3 and 24 h, respectively, after infection with both the LO-R6J20 and the LO-T7-1 RVVs; lanes 4 and 5, HCV core protein from HCV-infected-patient sera; lanes 3 and 6, HCV-negative sera. MW, molecular weight markers.
