  • Method for reducing non-specific aggregation of latex microparticles in the presence of serum or plasma
    Patent number: 6927071
    Abstract: A particle-enhanced assay for determining an analyte in a test sample in which an additive for reducing non-specific particle aggregation is added in an amount to substantially reduce non-specific aggregation. The additive is selected form the group consisting of triethanolamine, trimethanolamine, N-butyldiethanolamine, 3-dimethylamino-2-methylpropyl chloride, N,N-dimethylglycine, N,N-dimethylguanidine, N,N-dimethylglycine ethyl ester, 3-dimethylaminopropionitrile, and N,N-dietylacetamide.

  • Bi-directional lateral chromatographic test device
    Patent number: 5006474
    Abstract: A chromatic test device for the performance of immuno- or chemical assays wherein a unitary planar fibrous filter body incorporates a sample application zone, a separation zone and a reaction zone and the application zone is in fluid communication with a first absorbent and the reaction zone is in fluid communication with a second absorbent to establish bilateral flow of the fluid component of the sample and of the analyte applied to the zones during the performance of an assay.
