Inducible HLA-E expression without other class I molecules. Flow cytometry of HLA-E, HLA-A*11 (present in WT Elf-1 cells) and HLA-BC expression in the presence (orange) or absence (light blue) of IFNγ treatment. Isotype control tracings are shown in red. Single cell suspensions of Elf-1 ESCs with each indicated B2M genotype were derived by trypsin digestion of IFN-γ-treated ESCs. See Supplementary Table 2 for full HLA genotypes.
