Figure 3. Conjugation increases sensitivity of responding T cells to limiting amounts of antigen.
Mice injected with CFSE-labeled OTI T cells were challenged with the indicated amounts of the various forms of antigen as shown. Three days after transfer of OTI T cells, cells from the dLN were isolated and the OTI T cells assessed for the loss of CFSE as an indication of the presence of antigen in the host. The histograms shown were gated on live, CD8+, SIINFEKL-Kb tetramer+ events. The data shown are representative of three independent experiments.
