Some IgG subclasses can activate complement via the classical pathway. Some subclasses act as targets for macrophages, eosinophils and [[Neutrophils|neutrophils]]. It is therefore the major antibody in tissue fluids and lymph. IgG specifically binds to antigens on bacteria, causing agglutination and opsonisation.
