Antibodies specific for CD16/CD32 (93), CD45 (30-F11), CD11c (N418), CD11b (M1/70), Ly6G (1A8-Ly6g), B220 (RA3-6B2), MHC-II (M5/114.15.2), CD3 (145-2C11), F4/80 (BM8), CD19 (eBio1D3) from eBioscience; Ly6C (HK1.4) and CD103 (2E7) from BioLegend were used. Data were acquired using an iCyt Synergy and analyzed with FlowJo (Tree Star). The percentage of Listeria-associated (GFP+) cells in each population was determined by using cells from mice infected with L. monocytogenes SD2001 as a negative gating control in each experiment as described previously (18 (link),19 (link)).
