Agglutination Techniques for Detecting Antigen–Antibody Reactions

Abstract

The agglutination reaction reflects multiple reactions that take place between macromolecules to form a complex, which may involve antigen–antibody interaction and which, through colloidal instability, may lead to precipitation. The formation of this complex leads to an increase in light scattering, which can be used to quantify one of the species participating in the reaction.
