Abstract
In a particle agglutination assay for an antigen (Ag), there is included in the mixture a limited amount of a substance which binds univalently with a proportion of the Ag present, that Ag which is so bound being unable then to cause agglutination of the particles. In this way, unusually large concentrations of Ag can be assayed in that a proportion of the Ag is bound to the univalent substance and the particle agglutination assay is in effect conducted on the smaller amount of Ag still remaining free in solution.
