Flow cytometric analysis of CD11c expression on C57BL/6 mouse splenic leucocyte subsets. Panel 1. Splenic Leucocytes. Mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with Alexa Fluor® 647 Rat Anti-Mouse I-A/I-E (Cat. No. 562367) and either BD Horizon™ BV421 Hamster IgG2, λ Isotype Control (Cat. No. 562629; Left Plot) or BD Horizon BV421 Armenian Hamster Anti-Mouse CD11c antibody (Cat. No. 565451/565452; Right Plot). Two-color flow cytometric contour plots showing the correlated expression of I-A/I-E versus CD11c (or Ig Isotype control staining) were derived from gated events with the forward and side light- scatter characteristics of viable leucocytes. Panel 2. Ly6G/Ly6C-negative Splenic Leucocytes. Mouse splenic leucocytes were similarly preincubated with Mouse BD Fc Block™ and stained with APC Rat Anti-Mouse CD45R/B220 (Cat. No. 553092/561880) and PerCP-Cy™5.5 Rat Anti-Mouse Ly6G/Ly6C (Cat. No. 552093) antibodies and either BD Horizon BV421 Hamster IgG2, λ Isotype Control (Left Plot) or BD Horizon BV421 Armenian Hamster Anti-Mouse CD11c antibody (Right Plot). Two-color flow cytometric contour plots showing the correlated expression of CD45R/B220 versus CD11c (or Ig Isotype control staining) were derived from Ly6G/Ly6C- events with the forward and side light- scatter characteristics of viable leucocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Flow Cytometer system.
