The bands at the 35%-medium and the 35–55% interface were pooled, washed and stained with a combination of various antibodies to stain different DC subsets, conventional CD11c+CD8α+, CD11c+CD8α− and plasmacytoid DC (CD11c−PDCA-1+).The top panels were gated on FSChiSSClo cells to show separate populations of CD11c+PDCA-1− and CD11c−PDCA-1+ cells.
