Abstract: The present disclosure relates to immobilization of a cell using a carboxylated surface by contacting the carboxylated surface with a sample comprising the cell for a sufficient time to permit the cell to bind to the carboxylated surface. The immobilized cell may then be separated from the remainder of the sample and further manipulated to isolate, concentrate, and/or analyze the cell or a component thereof.

Abstract: A vial retainer system for an automated processing apparatus. The vial retainer system includes a track mounted to the processing apparatus, a rack adapted to slide in a longitudinal direction on the track, and a vial retainer positioned over the rack. The rack is movable in a distal direction to install the rack on the processing apparatus, and in a proximal direction, opposite the distal direction, to remove the rack from the processing apparatus. The rack is adapted to hold one or more vials in an upright orientation. The vial retainer has one or more a sloped surfaces inclined such that a distal end of each sloped surface is closer to the track than a proximal end of each sloped surface.
Abstract: An automated assay processing method including transferring a first number of samples from respective sample containers to a first intermediary vessel, determining the testing adequacy of a second number of samples in a second intermediary vessel, preparing a third number of samples in a third intermediary vessel for downstream testing; and transferring a fourth number of samples from a fourth intermediary vessel to an output sample tray. These steps are all performed essentially simultaneously within the duration of a single clock cycle and are repeated during one or more subsequent clock cycles. The clock cycle may be relative to each intermediary vessel. The clock cycle also may be universal to the first, second, third and fourth intermediary vessels.

Abstract: A sample adequacy measurement system having sample tubes and a housing having a receptacle to receive the sample tubes. The housing has sample adequacy measurement stations that each have a light source and a sample detector. The light source generates an illumination beam directed into one of the sample tubes. The sample detector is positioned along the tube, and receives at least a portion of the illumination beam scattered by turbidity in the sample tube. The detector is positioned at the end of an emitted beam path that extends in a plane that is perpendicular to the vertical direction and is oriented at a non-perpendicular angle with respect to the longitudinal axis of the sample tube unit. This reduce the likelihood that the emitted beam will pass through a damaged portion of the respective one of the sample tubes by passing the light through a protected portion of the tube.

Abstract: A reagent cabinet for an automated processing apparatus. The reagent cabinet has a housing, and a drawer slidably mounted in the housing. The drawer has a lower deck adapted to receive a fluid reservoir, and an upper deck located above the lower deck and adapted to receive a fluid supply container. A supply connection hose is provided to selectively connect the fluid supply container to the fluid reservoir. A reservoir connection hose is provided to selectively connect to the fluid reservoir and to convey fluid from the fluid reservoir to a downstream location outside the cabinet. A pump is mounted on the drawer. The pump is adapted to convey fluid through either the supply connection hose or the reservoir connection hose.

Abstract: The present invention relates to an accurate, sensitive, and efficient sequential or concurrently sequential method for molecular diagnosis of human papillomavirus (HPV)-based disease, where the method improves the accuracy and reliability of diagnostic and prognostic assessments of HPV-based disease. The method of the invention comprises a primary screen of a sample for HPV nucleic acids, followed by a secondary screen for molecular markers, such as proliferation and cell cycle control group protein markers. The sequential or concurrently sequential method significantly reduces the number of false positive results.

Abstract: A rack for an automated processing system. The rack includes a number of wells adapted to hold at least a first sample container having a first size, and a second sample container having a second size. The second size, which may be a diameter, a height, or both, is substantially different from the first size. A structure joins the wells. The rack is adapted to fit in an automated processing system that is adapted to remove both the first sample container and the second sample container from the rack.
Abstract: Methods and materials for determining the presence of at least one nucleic acid in a sample are provided, said methods comprising (1) a purification step using sequence specific hybrid capture; (2) an amplification step; and (3) a detection step comprising contacting the target nucleic acid with a plurality of detectably labeled nucleic acid detection probes, wherein each (a) bears a different detectable label from the other detection probes, and/or (b) has a different melting temperature from probes bearing the same detectable label. Also disclosed are compositions and kits for use in such a method.
