FIGURE 2.
Myeloperoxidase release by human monocytes. Myeloperoxidase activity in cell culture supernatants was measured by a fluorometric procedure after 3 h (A) or 24 h (B) of TPA stimulation in the presence or absence of CM (mean ± SD from 4 separate experiments with cells from separate donors). ++P < 0.01 compared to control (B: nonstimulated cells); ∗∗P < 0.01 compared to TPA. RFU, relative fluorescence units.
