FIG. 2.
MHC class I protein expression is regulated in an allele-specific manner in L929 cells. L929 cells were infected for 16 h and then stained for FACS analysis by using antibodies against Dk (A), gB (B), or Kk (C, D, and E; with monoclonal antibodies 16-3-1N, 11-4.1, and AF3-12.1.3, respectively). Lines: dotted, anti-mouse antibody alone; light, mock-infected cells; dark, infected cells.
