Cellular distribution of 440c antigen within murine splenocytes. (A) In total splenocytes, mAb 440c recognizes subsets of CD11c⁺ and Ly-6C⁺ cells, but not CD11b⁺, CD3⁺, CD19⁺, or DX5⁺ cells. (B) Within CD11c-enriched splenocytes, mAb 440c recognizes a Ly-6C⁺/B220⁺/CD8α^hi/lo/CD11b^- subpopulation. Plots represent gated CD11c⁺ cells. (C) mAb 440c recognizes only CD11c⁺/Ly-6C⁺ cells within splenocytes derived from mice that have been injected intraperitoneally with MCMV.
