Cells were stained with fluorochrome-conjugated monoclonal antibodies and 2.4G2 blocking antibody and incubated in the dark for 30 min on ice. For CD1d tetramer staining, cells were incubated in the dark for 15 min at room temperature followed by 15 min on ice. Flow cytometric analysis was performed on a FACSAria (BD Biosciences) or a MACSQuant (Miltenyi Biotec). Data were analyzed using FlowJo (Tree Star).
