Antibodies can inactivate an antigen in many ways, including complement fixation, neutralization, and opsonization.

Question

Quizplus · Accepted Answer

Antibodies can inactivate an antigen through complement fixation, where the antibody binds to the antigen and activates the complement system, leading to destruction of the antigen. Antibodies can also neutralize antigens by blocking their activity or binding sites, and can opsonize antigens by marking them for destruction by phagocytic cells.
