The trimer provides a surface for interaction between the antigen-antibody complex and other complement components.

These viruses are phagocytosed as antigen-antibody complexes, and degraded by macrophages.

The main activators of the Classical Pathway are antigen-antibody complexes.

Ability of C3b to bind to antigen-associated Ig would work effectively against antigen-antibody immune complexes to make them soluble.

The quantity and concentration of insoluble antigen-antibody complexes at the outer edge of the circle increases with time.

Analogously, in medicine, coprecipitation is specifically the precipitation of an unbound "antigen along with an antigen-antibody complex".

The protein-protein docking benchmark contains examples of enzyme-inhibitor, antigen-antibody and homomultimeric complexes.

The precipitin reaction is based upon the interaction of antigen with antibody leading to the production of antigen-antibody complexes.

The complement system is a system of serum proteins that react with antigen-antibody complexes.

These antigen-antibody complexes are thought to be caused by excessive exposure to bacterial antigens (especially peptidoglycans).
