Abstract: An apparatus and method of aligning a capillary (10) with respect to a radiation source (26). More particularly, the capillary is aligned with a laser beam (29) for laser induced fluorescence detection. The scatter or transmitted light pattern of the laser beam (29) with respect to the capillary (10) tube is utilized to determine optimum alignment. Photosensors (97, 99) may be implemented to detect the light pattern which represents optimum alignment. For dynamic alignment during electrophoresis, the photosensors provide feedback to a controller (124) which controls a positioning mechanism (122) with a plano-convex lens (120) for alignment of the capillary (10).

Abstract: Specific binding assays for measuring the concentration of an analyte in a sample involve forming a complex comprising a solid support, the analyte or an analogue of the analyte, and an enzyme. The enzyme is used to cleave non-isotopic labels that are directly detectable from a substrate/label conjugate to provide a plurality of released labels in the free state, which are then separated from conjugate containing unreleased label. The released labels are detected for measuring the concentration of the analyte in the sample. Preferably the analyte or analogue is connected to the solid support by a cleavable bond, so that the enzyme can be separated from the solid support for use in the enzymatic cleaving of labels from the conjugate. This preferred version reduces the adverse effect of non-specific binding on the sensitivity and accuracy of the assay.

Abstract: A competitive binding assay for vitamin B12 in a test sample gives a steep dose-response curve in the clinically significant concentration regions, yielding great accuracy. The assay uses immobilized vitamin B12 to compete with the vitamin B12 in the test sample for a binding partner. The quantity of the binding partner bound to the immobilized vitamin B12 can be measured and is inversely proportional to the concentration of free vitamin B12 in the test sample. The binding partner is typically biotinylated intrinsic factor prepared so that substantially all the molecules of intrinsic factor are biotinylated and the binding activity of the intrinsic factor for vitamin B12 is not diminished. The bound biotinylated intrinsic factor can then be determined by reacting it with avidin coupled to a reporter group. The reporter group is typically an enzyme such as horseradish peroxidase, but can be another detectable label. The immobilized vitamin B12 is typically bound to a solid support such as diazotized amine-derivatized beads, and can be bound through a protein linker. Other binding partners such as anti-vitamin B12 antibody are also usable. The binding partner can be labeled directly with the reporter group. The method is adaptable to the assay of serum, and methods of inactivating endogenous vitamin B12-binding proteins in serum are described.

Abstract: The present invention provides an improved rotor for a centrifuge that operates by centrifugal elutriation. The rotor consists of a chamber assembly, a disk assembly, and a quick release mechanism. The chamber assembly is relatively light and it includes one or two separation chambers, tubing and a rotating seal. The disk assembly consists of the relatively heavy support structure. The two piece construction facilitates handling the parts of the rotor that generally need to the autoclaved. The chamber assembly has a novel structure that allows the rotor to easily be configured for operation with one or two chambers. The disk assembly has a unique strain relief that prevents structural cracking. The quick release mechanism is held in the latched position by centrifugal force during operation of the rotor.

Abstract: A bidentate conjugate has two different chemical moieties, or bidentate members, attached through an adequate spacer moiety. Each bidentate member acts as a small molecule ligand and is capable of specifically binding to a different macromolecular substance. The bidentate members are relatively small molecules, usually less than about 7,000 Daltons in size. The spacer moiety is selected so that both bidentate members can simultaneously bind to their respective specific binding partners. Where the specific binding partners are multivalent, large complexes can be formed. The formation of these complexes can be inhibited by the presence of an unconjugated monovalent bidentate member, such as free analyte from a test sample. The bidentate is of particular use in turbidimetric or nephelometric inhibition immunoassay procedures.

Abstract: An analysis system including an ion selective electrode assembly, a sample container and a transport mechanism. The electrode assembly includes a reference electrode within a reference gel-filled well and ion selective electrodes disposed on an elongated portion of the electrode assembly. The sample container includes a body defining a plurality of reservoirs and a slot retaining an absorbant wiping and/or blotting material. The electrode assembly may be removably fixed relative to the transport mechanism. The transport mechanism includes a support table adapted to receive the sample container. The support table moves relative to the electrode assembly under the control of a cam to sequentially position the elongated portion of the electrode assembly within the reservoirs and the slot of the sample container.
