The medians of the reported percentages of MULTIMER-positive CD8-positive cells for each antigen-donor combination are shown in the table. These results are stratified by condition (with and without the inclusion of a dump channel). Results obtained using two MULTIMERS in four donors stratified by use of a DUMP channel. For all sixteen experimental conditions the median of the reported values for MULTIMER+ CD8+ cells for all experiments are displayed. The asterisk indicates a negative control donor.
