Abstract: Nucleic acid probes are immobilized on polystyrene surfaces such as the wells of microtiter plates for use in solution phase nucleic acid sandwich hybridization assays, particularly those using large branched DNA amplification multimers, by: (a) cleansing the surface by washing it sequentially with a strong acid, a strong base, and water, (b) passively adsorbing a polypeptide having primary amino groups onto the cleansed surface, and (c) covalently bonding the probe to the adsorbed polypeptide via a base-stable bifunctional crosslinking agent, and (d) subjecting the surface to conditions that simulate the hybridization conditions used in the assay.

Abstract: The entire genome of the hepatitis D virus has been shown to be a circular single-stranded RNA of 1679 bases. Several open reading frames in both the genomic and complementary strands indicate possible protein products. The products encoded in one open reading frame, ORF5, are identified as viral polypeptides p24.sup..delta. and p27.sup..delta., of which the nuclear .delta. antigens in HDV infected liver is comprised. These products, as well as others encoded in ORFs 1, 2, 6, and 7 are produced in recombinant expression systems. The ORF5 products, in particular, are useful for HDV diagnosis and vaccines.

Abstract: A collision construct is provided that contains a first regulatory sequence containing a first promoter linked to a reporter gene which is also linked to a second regulatory sequence containing a second promoter such that the reporter gene is under regulatory control of the first promoter. The direction of transcription under the first promoter is opposite the direction of transcription under the second promoter and activation of the second promoter interferes with reporter gene activity. The collision construct is used to screen inhibitors of the second regulatory sequence and the second promoter whereby a functional inhibitor causes an enhanced signal of the reporter gene. Vectors, host cells and kits containing the collision construct are provided, as well as methods for producing the collision construct, the vectors and host cells, and methods for screening candidate inhibitors for their ability to inhibit target promoter activities.

Abstract: An evanescent wave system and method including an optical sensor for use in assaying a reference material and at least one molecular species or analyte in a test medium or test sample for diagnostic and other applicable purposes. The sensor includes a waveguide for propagating a radiation input along its length. The radiation input causes evanescent electromagnetic waves that are capable of stimulating output emissions that are indicative of a reference material and of one or more molecular species or analytes. By comparing the emission(s) indicative of the reference material to the emission indicative of the presence of the molecular species or analyte, the presence and concentration of the molecule in the sample can be determined. The reference material provides for normalization and/or calibration of the system.

Abstract: A magnetic conveyor system for transporting test samples in tubes disposed in a sample rack having a magnetic or magnetically attractive region is described. The magnetic conveyor system includes a drive system, a magnet coupled to the drive system and movable in response to the drive system and a tray having a first surface adapted to receive the sample rack. The magnet is spaced a predetermined distance from the first surface of the tray such that the magnet provides a magnetic force at the surface of the tray. The magnetic force engages the magnetically attractive region of the sample rack disposed on the tray to thereby move the sample rack along the first surface of the tray in response to movement of the drive system. When the tray reaches the end of the rack it is moved onto a processing queue tray where it is available for test purposes. A barcode reader reads a bar code on each test sample as it is placed on the process queue to identify one or more tests to perform.

Abstract: The detection of the IS6110 insertion element in a clinical specimen is a rapid way of diagnosing infection by Mycobacterium tuberculosis. A reliable diagnostic test for tuberculosis based on the IS6110 DNA is described in this disclosure. A "Universal" specimen preparation protocol that eliminates live organisms and purifies nucleic acids from all types of clinical specimens is described. Two nucleic acid primers designed to amplify IS6110 DNA with high specificity in a polymerase chain reaction are also described. The amplified IS6110 DNA is identified by a restriction endonuclease and electrophoresis based assay. The identification process also renders the DNA unamplifiable in a subsequent PCR, thereby reducing the possibility of contaminating other specimens. Time, labor and cost is minimized, while user safety and test reliability are maximized.
