FIG. 1.
PRV infection of L929 cells does not affect overall MHC class I protein levels. L929 cells were infected for 16 h and then stained for FACS analysis, using antibodies against Dk and Kk (monoclonal antibody 16-3-1S) (A) β2-microglobulin (B), or viral glycoprotein gB. Lines: dotted, anti-mouse antibody alone; light, mock-infected cells; dark, infected cells.
