Minicores circulate in blood. (A) Purification scheme isolating core and minicores. (B) HCV RNA was enriched in the heparin/ Mn+2 pellet fraction. Error bars represent standard error of technical triplicates. (C) Minicores were detected by western blot in 4 patients with HCV (lanes P1‐P4) and not in 2 normal controls (lanes N1, N2). Cell culture lysate of infected cells served as a positive control (lane C). (D) Duplicate western blots of sample P4 probed with antibodies directed either to the C‐terminal or N‐terminal portion of the core protein confirmed the identity of minicores. Abbreviation: MW, molecular weight; sup, supernatant; term, terminus.
