  • Stabilization of particle reagents
    Patent number: 5981296
    Abstract: Stabilized particle reagents suitable for use in turbidimetric immunoassays are disclosed. The stabilized particle reagents contain functionalized polymer particles in which the surface of the particle has been modified with a molecular surface modifier having the structure:R(OCH.sub.2 CH.sub.2).sub.n NH.sub.2in which: R is --H, --CH.sub.3 or --CH.sub.2 CH.sub.3, and n is an integer between 2 and 10, inclusive. The stabilized particle reagents are resistant to premature or spontaneous aggregation during preparation or storage.

  • Luminescent specific binding assay
    Patent number: 5876935
    Abstract: A luminescent specific binding assay method is used for detecting an analyte in whole blood. The assay is a heterogeneous sandwich or competitive assay in which a first binding reagent is labeled with a luminescent photoprotein and an immobilized second binding reagent serves as a capture reagent. The luminescent photoprotein, upon activation, emits light which may be detected by a luminescence detector. The assay is rapid, sensitive and may be performed on small sample volumes.
