Samples were stained with a 2.4G2 blocking antibody and monoclonal antibodies in 1% PBS-serum for 20 minutes on ice in the dark. For samples stained with CD1 tetramer, cells were incubated for 15 minutes at room temperature in the dark, followed by 15 minutes on ice in the dark. Samples requiring intracellular staining were then fixed and permeabilized using CytoFix/CytoPerm (BD Biosciences) and stained with intracellular antibodies for 15 minutes on ice in the dark. Events were collected on either a FACSAria (BD Biosciences) or a MACSQuant (Miltenyi Biotec). Data were analyzed using FlowJo (Tree Star Inc.).
