The mean and standard deviations are derived from results on two separate experiments; the results from each experiment represent the average of triplicate wells (or more than 12 wells in the case of LMP2 peptide-responsive CD8+ cells) with the same number of responders per well.
The frequency of LCL-responsive CD8+ cells is also presented as the number of spots/106 PBMC for comparison with peptide-responsive CD8+ cells. This is estimated by: (number of spots/106 CD8+ cells) × (% of CD8+ cells among PBMC). The percentage of CD8+cells among PBMC is obtained by positive selection of CD8+cells with Dynal-beads. The mean and standard deviation of 2 CD8+ cell selection are presented in parentheses.
This average is derived from both HLA-A2 and non HLA-A2 EBV (+ve) donors.
