Tetramer staining of patients and peptide-expanded T-cell lines.

Rows 1 to 5 refer to patients 1 to 3, 6, and 9, respectively, in the Tables; for details see Results section. (A) Left-hand panels (1-5A) display the levels of tetramer-positive cells specific for HLA-A3 and peptide KQSSKALQR from the peripheral blood. (B) Central panels (1-5B) show the levels of tetramer-positive cells specific for HLA-A2 and the CMV peptide NLVPMVATV. (C) Right-hand panels 1C and 3C show the levels of tetramer-positive cells specific for HLA-A3 and the peptide KQSSKALQR from in vitro culture following peptide stimulation and expansion.
