FIG. 6.

HAstV-1 CP and virions have a modest effect on alternative pathway activity. NHS or C2D serum was incubated with rabbit RBCs in Mg-EGTA-GVBS buffer alone or in the presence of 6.3 μg CP (A) or HAstV-1 virions (30 μl of cell lysate, corresponding to 1.03 × 10⁸ genome copies) (B). Hemolysis was standardized to 100% for each serum in the absence of CP or virus. Data are the means for three (A) or six (B) independent experiments. Error bars denote SEM.
