Abstract: Methods for selecting tag-oligonucleotide sequences for use in an in vitro nucleic acid assay. The selected tag sequences are useful for nucleic acid assay wherein interference between the nucleic acid sequences is the assay is to be controlled. Selected tag sequences are incorporated into nucleic acid assay to improve the performance of and/or minimize any interference between nucleic acids in the assay compared to untagged assays.

Abstract: A device for releasably holding an elongated object, such as a test tube, in a predetermined orientation includes a gripping element configured for circumferential expansion and contraction with respect to the object. An actuator element coupled to the gripping element is configured to effect circumferential expansion of the gripping element to an expanded configuration able to receive an end of the elongated object. A locking mechanism coupled to the actuator element is configured to lock the actuator element in a position holding the gripping element in the expanded configuration. A lock release mechanism is configured to be triggered by an elongated object inserted into the expanded gripping element and to release the locking mechanism, thereby allowing the biased gripping element to return to a contracted configuration gripping a portion of the object. The device and an object held thereby can be conveyed on a conveyor.

Abstract: An apparatus configured for mixing the contents of one or more fluid containers includes a fluid container support platform configured to hold one or more fluid containers. The fluid container support platform is configured to index the container to one or more specified locations and to be moved in an orbital path about an orbital center independently of the rotation about the central axis of rotation. The apparatus further includes an indexing drive system configured to effect indexing movement of the container support platform and a vortex drive system configured to effect powered orbital movement of the container support platform about the orbital center. An evaporation limiting insert placed within containers reduces exposure of the fluid contents of the container to atmospheric air, thereby reducing susceptibility of the fluid contents to evaporation.

Abstract: Compositions, methods and kits for detecting Chikungunya viral nucleic acids. Particularly described are methods for detecting very low levels of the viral nucleic acids using nucleic acid amplification.

Abstract: The disclosed invention is related to methods, compositions, kits and isolated nucleic acid sequences for targeting Adenovirus nucleic acid. Compositions include amplification oligomers and/or detection probe oligomers. Kits and methods comprise at least one of these oligomers.

Abstract: The present invention provides compositions, kits and methods for the selective hybridization and capture of a specific target nucleic acid. The specific target nucleic acid may be present in a heterogeneous mixture of nucleic acids. Selective hybridization and capture provides a target nucleic acid that is substantially free of non-target and/or contaminating nucleic acids. Target nucleic acids that have been selectively hybridized and captured using the current invention are then used in subsequent analysis, wherein the presence of non-target and/or contaminating nucleic acids that interfere with said subsequent analysis have been substantially reduced or eliminated, thereby providing improved analysis results.

Abstract: A receptacle includes an upper portion having a cylindrical portion and an open end and a lower portion depending from the upper portion, where the lower portion is tapered and has a closed bottom end. The receptacle may include a radially-extending annular ring with a flat or sloped bottom surface and disposed on an outer surface of the receptacle at a transition between the upper portion and the lower portion and/or a radially-projecting lip circumscribing the open end, which may be configured for inter-locking engagement with a mated cap inserted into the open end of the upper portion. Embodiments may include one or more longitudinally-oriented grooves formed in an inner surface of the upper portion. The receptacle may be a unitary plastic structure.

Abstract: Provided are compositions, kits, and methods for the identification of Salmonella. In certain aspects and embodiments, the compositions, kits, and methods may provide improvements in relation to specificity, sensitivity, and speed of detection.

Abstract: A system for separating an analyte from other components of a sample includes a receptacle holding station and a magnetic separation station. The receptacle holding station includes one or more stationary, permanent magnets positioned to apply a magnetic field to the contents of a receptacle held stationary within the receptacle holding station. The magnetic separation station includes one or more permanent magnets and is configured to perform a magnetic separation procedure on the contents of a receptacle transported from the receptacle holding station to the magnetic separation station. The magnetic separation procedure includes isolating an analyte immobilized on a magnetically-responsive solid support within the receptacle and removing other components of the sample from the receptacle. The magnetic separation station is configured to provide relative movement between the receptacle and the one or more permanent magnets after the receptacle is transported to the magnetic separation station.

Abstract: A receptacle comprises opposed members, a plurality of chambers having perimeter walls defined by seals formed between the opposed members and portals interconnecting the chambers, and a rigid frame supporting the opposed members at their peripheral edges. The frame comprises a front frame portion and a rear frame portion, and the peripheral edges of the opposed members are retained between the front and rear frame portions. An inlet port extends between the front and rear frame portions and is in fluid communication with one of the chambers.

Abstract: A method of processing a sample in a receptacle comprising a plurality of chambers. Each of the chambers is connected to at least one other chamber by a portal and at least a first one of the chambers is formed of a flexible material.

Abstract: A receptacle transport mechanism comprises a body, a plunger configured to be movable with respect to the body, and one or more limbs movably attached to the body and positioned in operative engagement with the plunger. The plunger is movable with respect to the body between a first position whereby engagement by the plunger with the one or more limbs positions a lower portion of each limb proximal to the body and a second position whereby engagement by the plunger with the one or more limbs extends the lower portion of each limb outwardly relative to the body.

Abstract: Disclosed are methods for amplifying a nucleic acid target region using an amplification oligomer comprising a target-binding segment and a heterologous displacer tag situated 5? to the target-binding segment. Initiation of an amplification reaction from the tagged amplification oligomer produces an amplicon comprising the displacer tag, such that once the complement of the displacer tag has been incorporated into a second amplicon, a displacer oligonucleotide having a sequence substantially corresponding to the displacer tag sequence is used to participate in subsequent rounds of amplification for displacement of an extension product primed from a site within the second amplicon 5? to the displacer priming site. Also disclosed are related kits and reaction mixtures comprising the displacer-tagged amplification oligomer and corresponding displacer oligonucleotide.

Abstract: Improved methods for use in nucleic acid amplification, including multiplex amplification, where the amplification is carried out in two or more distinct phases are disclosed. The first phase amplification reaction preferably lacks one or more components required for exponential amplification. The lacking component is subsequently provided in a second, third or further phase(s) of amplification, resulting in a rapid exponential amplification reaction. The multiphase protocol results in faster and more sensitive detection and lower variability at low analyte concentrations. Compositions for carrying out the claimed methods are also disclosed.
