Question

What is the process by which antibodies convert soluble antigens into insoluble complexes for removal from the body?

Options

• Agglutination

• Complement fixation

• Precipitation

• Opsonisation

Answer 1

Precipitation is the antibody function that converts soluble antigens into insoluble complexes. These insoluble complexes are then more easily removed from the bloodstream through filtration and phagocytosis, reducing the harmful effects of circulating antigens.
