Immune complex assay

摘要

Method for the estimation of immune complex and analysis of a constituent thereof. Method comprises a latex particle agglutination test in which a reagent comprising low affinity latex particles is contacted with a sample containing immune complex. The low affinity coated latex particles are latex particles coated with IgG antibodies to the complex constituent and may be prepared by contacting latex particles with the IgG antibodies, the latter optionally being substituted with a coupling agent. One or more reagents are conveniently provided in kit form.
