Fig. 4. Pentamer staining on HLA-A2-positive donors.

Fig. 4

a Pentamers against 2 RVFV HLA-A2-directed epitopes (ILD and VLS) were labeled on both APC and PE and were incubated with PBMCs from various donors. A sample from a control donor who is HLA-A2-positive but unvaccinated is also included; this donor has influenza-specific CD8 T cells but no RVFV-specific CD8 T cells. The pentamer frequencies for each donor are shown in b. Dotted lines show the background value for each pentamer based upon the background signal observed in the HLA-A2-negative donor, RHI-7.
