“Th subset” and “sorting” panels have been described in
previous publications [17 (link), 18 (link)]. The “Th subset” panel included the following
additional reagents: CCR6Ax488 (clone TG7/CCR6); CCR10PE (clone
6588-5, both from BioLegend); CXCR3PE-Cy5 (clone 1C6/CXCR3); and
HLA-DRPE-Cy5.5 (clone TÜ36, both from BD Biosciences). The
“sorting” panel included the following additional reagents:
CCR6BV605 (clone G034E3); CCR4PE-Cy7 (clone TG6/CCR4, both from
BioLegend); CD4APC (clone RPA-T4, BD Biosciences); as well as TCR-Vβ12
(clone VER2.32.1); TCR-Vβ14 (clone CAS1.1.1.3); and TCR-Vβ17 (clone
E17.5F3.15.13) conjugated to FITC (Life Technologies) at the VRC; and TCR-Vβ1
(clone BL37.2); TCR-Vβ2 (clone MPD2D5); TCR-Vβ7 (clone ZOE);
TCR-Vβ13.6 (clone JU74.3); TCR-Vβ16 (clone TAMAYA1.2); and
TCR-Vβ22 (clone IMMU546) conjugated to Ax594 (Life Technologies) at the VRC. All
unconjugated TCR-Vβ Abs were obtained from Beckman Coulter. For intracellular
staining, cells were treated with BD Cytofix/Cytoperm Permeabilization Solution (BD
Biosciences), except for the Treg panel, where the Foxp3 Staining Buffer Set
was employed (eBioscience). Data were acquired on an LSR II (BD Biosciences) using a
high-throughput system (HTS).
