High-power (original magnification × 400) photomicrographs of immunolocalization of neutrophil-derived COX-2 protein. Human neutrophils (1 × 107 cells) were cultured for 18 hours with 10 ng/mL of IL-10 or IL-4 in the presence or absence of LPS (100 ng/mL). The cells were deposited on a glass slide and stained with anti–COX-2 MoAb (A, medium; B, LPS; C, LPS + IL-4; D, LPS + IL-10) or control antibody (E).
