Figure 1 Immunohistochemical detection of HCV-encoded protein in infected 7721 cells. Positive reaction (yellow) with anti-NS₃ (A) and anti-CP₁₀ (B) in 7721 cells, were scattered in the lobules (SP method, original magnification, A × 200, B × 400). Lack of staining with the same antibody in uninfected 7721 cells processed at the same times and 7721 incubated with oormal serum (C).
