Usage: technical; immunology; medical

Examples

• The opsonified bacteria were more readily engulfed by the white blood cells.
• In the laboratory, opsonified pathogens showed increased susceptibility to phagocytosis.
• The immune system's opsonified targets were efficiently cleared from the bloodstream.
• Researchers studied how opsonified microorganisms interact with macrophages.
