Panel A shows the preliminary gating strategy for isolating immune cells (Time, singlets, debris dump, live/dead staining). Subsequent gating is as follows: pDCs (Lin-, F4/80−, MHCII+, B220+/SiglecH+); cDCs (Lin−, F4/80−, MHCII+, CD11c++, CD11blo); B cells (CD19). All flow experiments utilized FMOs, found in Supplementary Figure 2. Panel B depicts differences in the % live of cDCs and pDCs.
