stained with a cocktail of leucocyte cell surface markers including the
following anti-mouse monoclonal antibodies: CD11b (Brilliant Violet 421 #101235
[1:1000]; PE #557397 [1:500]), CD49d (FITC #103605 [1:1000]), Gr1 (PerCP-Cy5.5
#552093 [1:1000]), Ly6C (PerCP #128028 [1:1000]), F4/80 (Alexa Fluor 700 #123130
[1:1000]), Ly6G (APC/Cy7 #127624 [1:500]), CD45 (V500 #561487 [1:500]) (all
Biolegend, San Diego, CA) and CD11c (APC #17-0114-82 [1:1000]) (eBioscience, San
Diego, CA). CountBright absolute counting beads (Molecular Probes, Eugene, OR)
were used to determine total cell number per sample, and propidium iodide was
used for viability. Data collection was performed on a BD LSR II Flow Cytometer
and data analysis performed using FACSDiva (both BD Biosciences, Franklin Lakes,
NJ). On the basis of forward and side scatter, propidium iodide staining, and
staining on unutilized wave lengths, the following events were eliminated:
debris, red blood cells, aggregates, dead cells and autofluorescence.
