    摘要: In one aspect, a diagnostic test system includes a housing, a reader, and a data analyzer. The housing includes a port for receiving a test strip. The reader obtains separable light intensity measurements from localized regions of an area of the detection zone exposed for optical inspection, wherein each of the localized regions is characterized by at least one surface dimension smaller than the first dimension. The data analyzer identifies ones of the light intensity measurements obtained from the at least one test region and computes at least one parameter from the identified ones of the light intensity measurements. In another aspect, the reader obtains a respective set of light intensity measurements from each of multiple corresponding regions of the exposed surface area of the detection zone, and the data analyzer computes at least one parameter from at least one of the sets of light intensity measurements.

    摘要: Non-leguminous crops, e.g. wheat, maize and rice, do not form nodules and are dependant for their nutrition on fixed nitrogen from the soil, or from chemical/nitrogenous fertilizers. The present invention provides non-leguminous plants and leguminous plants, including legumes that fail to nodulate with Rhizobia, with bacteria that enable them to fix nitrogen endophytically. Therefore, the plants contain nitrogen fixing bacteria the bacteria being located intracellularly in living plant cells.

    摘要: An assay test strip includes a flow path, a sample receiving zone, a label, a detection zone that includes a region of interest, and at least one position marker. The at least one position marker is aligned with respect to the region of interest such that location of the at least one position marker indicates a position of the region of interest. A diagnostic test system includes a reader that obtains light intensity measurement from exposed regions of the test strip, and a data analyzer that performs at least one of (a) identifying ones of the light intensity measurements obtained from the test region based on at least one measurement obtained from the at least one reference feature, and (b) generating a control signal modifying at least one operational parameter of the reader based on at least one measurement obtained from the at least one reference feature.

    摘要: The invention relates to devices for performing single step assays for the determination of the presence or absence of an analyte in a liquid sample, and methods of determining the presence or absence of such analytes using such devices. Devices disclosed comprise a labeled analyte-binding reagent reversibly-immobilized on a non-porous solid material, which solid material is in physical contact with a dry porous carrier bearing an immobilized analyte-binding reagent. Also provided are quantitative assay devices.

    摘要: A test device and method for determining the presence or absence of an analyte in a fluid sample, the test device including a support bearing a mark thereon, and a matrix defining an axial flow path. In operation, an observation area in the test device becomes transparent, thereby allowing the user to view a mark that is present on a support that is disposed beneath the observation area. Typically, the mark on the underlying support is configured as a minus (−) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (−) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (+) signal that is visible to the user.
