Craig (11) proposed previously that the immunospecific binding of antibody fragments to analyte-modified particles changes the colloidal properties of the latex particles, thus triggering agglutination without the need for bridging of particles by the bivalent antibody.
The reaction between a polyvalent antigen and a bivalent antibody is generally assumed to lead to aggregate formation through bridging by the antibody between antigen molecules, the amount of light scattering reflecting aggregate formation and the amount of antigen and (or) antibody present.
