The following mAbs were used for staining and flow cytometric measurements: CD3-VioGreen (BW264/56), CD4-allophycocyanin-Vio770 (VIT4), CD8-PE-Vio770 (BW135/80), CD14-peridinin chlorophyll protein (PerCP) (TÜK4), CD20-PerCP (LT20), CD27-FITC (M-T271), CD28-FITC (15E8), CD45RA-VioBlue (T6D11), CD45RO-FITC (UCHL1), CD62L-FITC (145/15), CD107a-PE (1D4B), CD127-FITC (MB15-18C9), CD137-allophycocyanin, CD137-PE (4B4-1), CD154-VioBlue (5C8), CD178-PE (NOK-1), CD197 (CCR7)-allophycocyanin, CD197 (CCR7)-PE (150503), CD279-allophycocyanin (PD1.3.1.3), anti-IL-2-PE-Vio770 (N7.48A), anti-IL-4-PE (7A3-3), anti-IL-17-FITC (CZ8-23G1), anti-IFN-γ-FITC, anti-IFN-γ-PE-Vio770 (45-15), anti-TNF-α-PE, and anti-TNF-α-VioBlue (cA2) (all Miltenyi Biotec).
Soluble biotinylated pHLA-A*0201 molecules loaded with WT137 (VLDFAPPGA), WT1126 (RMFPNAPYL), WT1187 (SLGEQQYSV), WT1235 (CMTWNQMNL), or cytomegalovirus (CMV) pp65495 (NLVPMVATV) were produced as described previously.14 (link) Tetramerization was achieved by binding to streptavidin-PE or streptavidin-allophycocyanin (both BioLegend, San Diego, CA). In each case, 2·5 × 106 cells were stained with 1 µg/ml tetramer for 45 min at 4°C.
Data were acquired using a MACSQuant flow cytometer and analysed with MACSQuantify software (both Miltenyi Biotec).
