  1. aCells from three different HLA-A2-homozygous donors (numbers 1, 4 and 5) were used
  2. bCells containing FITC-labeled influenza virus-derived green fluorescence after addition of ethidium bromide to quench FITC-derived green fluorescence external to the cells. 104 cells were analyzed for each determination
  3. cMonocytes/macrophages were identified by forward and side light scatter as well as expression of CD14
