    摘要: This invention relates to a detection system for measuring a fluorescent signal in a fluorescent assay. The system comprises a probe having a small sensing surface bound with a fluorescent label, and a light source and a detector both mounted at the proximal side of the sensing surface of the substrate. The invention also relates to a method for detecting an analyte in a liquid sample using a probe tip having a small surface area (≦5 mm) and a high molecular weight polymer (≧1 MD) having multiple binding molecules and multiple fluorescent labels. The binding reaction is accelerated by flowing the reaction solutions laterally and moving the probe tip up and down in the reaction vessels. The invention furthers relates to a fluorescent labeling composition comprising a cross-linked Ficoll molecule having a plurality of binding molecules and a plurality of fluorescent labels.

    摘要: A method for inhibiting hyperplasia at an anastomotic junction of a vascular fistula or vascular graft comprises exposing the anastomotic junction to vibrational energy at a mechanical index and for a time sufficient to inhibit hyperplasia. Kits are described comprising the catheter or a probe suitable for performing the methods together with instructions for use setting forth the methods. The methods and kits are particularly suitable for treating anastomotic junctions formed to provide vascular access for hemodialysis, hemofiltration, and the like. The methods and kits are also suitable for treating other vascular grafts, such as those formed during cardiac bypass graft surgery, vascular repair, and the like.

    摘要: A method of assaying bone collagen degradation activity in a human subject. In the method, a human urine sample is reacted with an antibody which (i) is capable of reacting immunospecifically with pyridinium crosslinks selected from the group consisting of native free pyridinoline and native free deoxypyridinoline, and (ii) has a ratio of reactivity toward the selected pyridinium crosslinks and urinary pyridinium peptides larger than 1,000 daltons in molecular weight, of greater than about 5:1. An immunocomplex forms between the antibody reagent and the selected pyridinium crosslinks which are present in the sample, and the amount of immunocomplex is measured. Also disclosed are antibody reagents and kits which can be used in the method.

    摘要: The system for transferring plasma to a test substrate comprises an applicator and the test substrate. The applicator includes a blood reservoir and a filter element which separates cellular components from the blood as plasma is passed to the test substrate. The test substrate includes an absorptive element which receives the plasma from the applicator. In one embodiment, measured amounts of plasma are transferred when the absorptive element becomes saturated, thus stopping the flow of plasma. In another embodiment, excess blood and cellular components are removed from the measured plasma by disengaging the applicator from the test substrate. In another embodiment, plasma transferred to the absorptive element is eluted from the absorptive element by subsequent application of an elution medium.

    摘要: Methods and apparatuses are described for determining the presence of an analyte in a sample suspected of containing the analyte. The method comprises contacting a concentrate of a determinable element capable of being detected by means of a semiconductive electrode with the electrode in the presence of a relatively large volume of an assay medium. The determinable element is present in the concentrate in the amount related to the amount of analyte present in the sample. The volume of the medium in diffusive communication with the concentrate is then reduced and the determinable element is detected by means of the effect that the determinable element has on the semiconductive electrode.
