anti-TCR Vα24-Jα18 (referred to as iNKT; clone 6B11), anti-CD3
(clone UCHT1), anti-CD4 (clone RPA-T4), anti-CD8 (clone RPA-T8), anti-CD34
(clone 561), anti-CD38 (clone HIT2, Biolegend) and anti-TCR
γ/δ(clone B1) from Biolegend, anti-TCR Vβ11 (Beckman
Coulter), anti-iNKT (BD Biosciences), CD1d tetramers loaded with PBS57, an
analog of α-GalCer (National Institutes of Health Tetramer Core
