Modulation of Human Colostrum Phagocyte Activity by the Glycine-Adsorbed Polyethylene Glycol Microspheres
Figure 2
Bacterial killing by colostral phagocytes. Phagocytes with PEG microspheres with adsorbed glycine internalized (panel (a)). The phagocytes were incubated with bacteria on a shaker 50 rpm for 30 min at 37°C. After washing at 4°C, cells were stained with acridine orange and analyzed by fluorescent microscopy. Orange-stained bacteria (dead) and green-stained bacteria (alive). Phagocytosis of bacteria (panel (b)) and bacterial killing (panel (c)).
