Agglutination-Inhibition Immunoassay

Other homogeneous immunoassays Several further homogenous assay formats have been developed that capitalize on the ability of antigen-antibody complexes to form detectable clusters or networks. Examples include the latex particle agglutination assay and the latex particle agglutination inhibition assay, in which the analyte or the antibody is conjugated to latex beads, and the analyte is quantified by virtue of its ability to promote or disrupt agglutination. Another example is the liposome immunoassay, in which analyte molecules are coupled to lipids,...
