  • Patent number: 9034657
    Abstract: A two step lateral flow assay method for identifying IgE antibodies in a sample comprises applying a sample to a sample port of a device, wherein the device is adapted to deliver the sample to a lateral flow matrix having a plurality of IgE antigen species immobilized at respective positions at a first location; allowing the sample to travel along the lateral flow matrix through the immobilized plurality of IgE antigen species to a second location downstream of the first location; and, after a predetermined period of time, applying liquid buffer to the lateral flow matrix to mobilize labeled reagent which is adapted to bind anti-IgE antibody and which is dried on the lateral flow matrix at a location upstream of the sample port delivery of the sample to the lateral flow matrix, and allowing labeled reagent mobilized by the liquid buffer to travel along the lateral flow matrix through the immobilized plurality of IgE antigen species and bind with any IgE antibody bound to the immobilized IgE antigen species, a

  • Patent number: 9034276
    Abstract: An oestrus detector 100 includes a reservoir portion 135 which contains a colored liquid. The detector 100 further includes a generally planar portion 110 that is attached to and sealed from the reservoir portion 135, except for an open or closed passage 111 in a seal line separating the reservoir portion 135 and the generally planar portion 110. In use the liquid is squeezed from the reservoir portion 135, through the passage 111, and into the generally planar portion 110, when the reservoir portion 135 receives pressure.

  • Patent number: 9034264
    Abstract: The present application provides apparatus and methods for determining the density of a fluid sample. In particular, it provides a sensor device which can be loaded with a fluid sample such as blood, and which further comprises at least one oscillating beam member or resonator. Exposure of the blood sample to clotting agents allows a clotting reaction to commence. The device allows the density of the sample fluid to be monitored with reference to the oscillation of the vibrating beam member, thus allowing the monitoring of the clotting of the fluid sample.

  • Patent number: 9017992
    Abstract: The invention provides compositions and methods for the detection of targets in a sample; in particular, an in situ hybridization (ISH) sample. Probes and detectable labels may be provided in multiple layers in order to increase the flexibility of a detection system, and to allow for amplification to enhance the signal from a target. The layers may be created by incorporating probes and detectable labels into larger molecular units that interact through nucleic acids base-pairing, including peptide-nucleic acid (PNA) base-pairing. Optional non-natural bases allow for degenerate base pairing schemes. The compositions and methods are also compatible with immunohistochemistry (IHC), immunocytochemistry (ICC), flow cytometry, enzyme immuno-assays (EIA), enzyme linked immuno-assays (ELISA), blotting methods (e.g. Western, Southern, and Northern), labeling inside electrophoresis systems or on surfaces or arrays, and precipitation, among other general detection assay formats.

  • Patent number: 9017622
    Abstract: A calibrator, for calibrating a sensor, has a calibration chamber for containing a calibration liquid. The liquid comprises water or an aqueous solution of an analyte to be sensed. A hydrogen peroxide-quenching material is provided exposed to the interior of the calibration chamber. The hydrogen peroxide-quenching material contacts the calibration liquid. After the calibration chamber containing the calibration liquid is sterilized by irradiation with gamma radiation, the hydrogen peroxide-quenching material decomposes any hydrogen peroxide formed in the calibration liquid to avoid adverse effects on a sensor placed in contact with the calibration liquid.
