Detection of CD46 (A), CD55 (B), and CD59 (C and D) on VV virion surface by immunogold labeling. HeLa cells infected with WR (5 pfu/cell) for 14 h (A–C) or HeLa cells inoculated on ice with purified WR IMV (20 pfu/cell) (D) were fixed and treated as described in Materials and Methods for preembedding immunogold labeling. (Bar = 100 nm.)
