FIG. 3.

Cell surface expression of D^k is reduced by an early PRV gene product, and K^k is increased by a late PRV gene product. L929 cell were infected with PRV strain Becker (A to F) or β-propiolactone-inactivated PRV strain Becker (G to I) in the presence (D to F) or absence (A to C and G to I) of PAA at 400 μg/ml for 16 h and then stained for FACS analysis by using antibodies against D^k and (A, D, and G), K^k (B, E [with monoclonal antibody 16-3-1N], and H [with monoclonal antibody 11-4.1]), or gC (C, F, and I). Lines: dotted, anti-mouse antibody alone; light, mock-infected cells; dark, infected cells.
