Analysis of pp65 mini-LCL–stimulated and control mini-LCL–stimulated T cells from the CMV⁺, EBV⁺ donor no. 4.

(A) Cytotoxic activities of the T-cell cultures, assayed on cultivation days 30, 53, 56, and 60 by chromium release. (B) Both T-cell populations were analyzed by tetramer staining on day 34. Tetramers used were IPS (pp65, B35-restricted), NLV (pp65, A2-restricted), RRIY (EBV EBNA3C, B27-restricted), YPL (EBV EBNA3A, B35-restricted), and HPV (EBV EBNA1, B35-restricted).
