  • Patent number: 8101429
    Abstract: This invention is directed to a lateral flow assay for detecting the presence of an analyte in a liquid test sample. The lateral flow assay represents an improvement in the ability to accurately and with high fidelity to detect the presence or absence of a target analyte in a liquid sample, in part, by encompassing a reference region of immobilized, non-diffusible analyte that allows for detection of any factors that interfere with the interaction and binding of the analyte to the labeled capture reagent. Any influences on the interaction and binding of the analyte that is free in solution in the liquid test sample to its complementary labeled reagent will be encountered in parallel in the binding between the immobilized analyte in reference region to the labeled reagent as it diffuses through the reference region. In one embodiment, the lateral flow assay of the invention is a urine-based human Chorionic Gonadotropin (hCG) assay.

  • Patent number: 8067246
    Abstract: A method and apparatus for use in a flow through assay process is disclosed. The method is characterised by a “pre-incubation step” in which the sample which is to be analyzed (typically for the presence of a particular protein), and a detection analyte (typically one or more antibodies bound to colloidal gold or a fluorescent tag) which is known to bind to the particular protein may bind together for a desired period of time. This pre-incubation step occurs before the mixture of sample and detection analyte come into contact with a capture analyte bound to a membrane. The provision of the pre-incubation step has the effect of both improving the sensitivity of the assay and reducing the volume of sample required for an assay. An apparatus for carrying out the method is disclosed defining a pre-incubation chamber for receiving the sample and detection analyte having a base defined by a membrane and a second membrane to which a capture analyte is bound.

Such proteins and molecules with increased half-lives have the advantage that smaller amounts and or less frequent dosing is required in the therapeutic, prophylactic or diagnostic use of such molecules.

  • Patent number: 8012742
    Abstract: A tube and float system for use in separation and axial expansion of the buffy coat is provided. The system includes a transparent, or semi-transparent, flexible sample tube and a rigid separator float having a specific gravity intermediate that of red blood cells and plasma. The sample tube has an elongated sidewall having a first cross-sectional inner diameter. The float consists of a main body portion and one or more support members protruding from the main body portion to engage and support the sidewall of the sample tube. The main body portion and the support members of the float have a cross-sectional diameter less than that of the first cross-sectional inner diameter of the tube when the sample tube is expanded, such as by centrifugation. The main body portion of the float together with an axially aligned portion of the sidewall define an annular volume therebetween.

  • Patent number: 8013134
    Abstract: The present invention relates to sensitive, rapid and convenient assays for detection and or quantification of one or more analyte(s) in solution using multivalent proximity probes. The proximity probes each comprise several binding moieties, such as antibodies, and associated nucleic acid(s). When the binding moieties have bound to their analyte(s), the nucleic acids on opposite proximity probes interact with each other and a signal is generated based on this interaction. The multivalent proximity probes are especially valuable for highly sensitive and specific protein detection.

  • Patent number: 8003407
    Abstract: The present invention relates to a lateral flow assay and system, including a test strip, for detection and quantification of analytes in samples, such as samples containing cells and fluid. In general, according to the present invention, a test strip for a lateral flow assay for detection of at least one analyte in a sample comprises: (1) a chromatographic strip, a sample filter, a fluid-impermeable barrier, and means for providing a mobilizable detectable agent that is capable of binding to the at least one analyte or to the capture agent after capturing the analyte to the chromatographic strip such that the mobilizable detectable agent migrates through the chromatographic strip and contacts sample that has passed through the sample filter and also has migrated through the chromatographic strip. The test strip allows detection with or without quantitation of an analyte in a sample containing whole cells.
