Question

Quizplus · Accepted Answer

The process by which soluble antigens combine with antibodies to form insoluble immune complexes is called precipitation. In this process, the clumping of the immune complexes makes them insoluble and they can be easily removed by phagocytic cells. Opsonization is the process by which particles are marked for phagocytosis. Activation is the process by which immune cells are stimulated to increase their activity. Agglutination is the clumping of cells, microorganisms or particles in response to the presence of antibodies. Neutralization is the process by which antibodies bind to and block the activity of toxins or viruses.
