ELISAs were performed using supernatants of cells exposed to CB-MPs or hydrolyzed CB dye. The concentrations are in pg/ml ± CI (α = 0.05). The three values per cell in the CB MP columns represent MCP-1, MIP-1α, and TNF-α responses to 10, 5, and 2.5% MP bed volumes, notated from top to bottom. For KC, the three values represent responses to 10, 3.3, and 1% bead volumes. ND, analysis not done. LL, concentration below the lower limit of quantification.
