  • Microparticle enhanced light scattering agglutination assay
    Patent number: 6828158
    Abstract: Reagents and the use of the reagents in a microparticle light scattering agglutination assay are disclosed. The reagents comprise a mixture of particles having relatively stronger light scattering properties and particles having relatively weak light scattering properties with respect to one another. The particles having strong light scattering properties carry a binding partner of high reactivity with the analyte. The particles having weak light scattering properties carry a binding partner of low reactivity with the analyte.
    Type: Grant
