Lymphocytes were assessed for binding of tetramer to CD8αβ+ T cells in whole blood.
PBLs were cultured with p11C and then tetramer binding to CD8αβ+ T cells was assessed.
PBLs were cultured with p11C and 7 days later p11C, C-M-specific lysis was determined in a standard 51Cr-release assay. Data represent % specific lysis at an E:T ratio of 2.5:1.
NT, not tested.
