Embodiments of a blood coagulation testing system can operate as an automated thromboelastometry system that is particularly useful, for example, at a point-of-care site. In some embodiments, the blood coagulation testing system includes a single-use cartridge component configured to measure and mix reagents with blood received from a blood sample reservoir. A mixing chamber in the single-use cartridge includes different reagent beads that, when exposed to a pre-determined volume of blood, dissolve and mix specific reagents with the blood. The assembled blood cartridge further includes configurations that are designed to prevent blood from prematurely mixing with reagent beads in the mixing chamber and to guide blood flow in the mixing chamber to dissolve reagent beads in a desired order. Thus, the mixture obtained from the mixing chamber can be readily utilized to generate results for the blood coagulation testing system.

The present invention relates to an immunoassay device and an immunoassay method. According to an aspect of the present invention, an immunoassay device includes a measurement unit provided with a detection unit disposed at one side of a stage accommodating cartridges having a plurality of wells to move in a direction, in which the plurality of cartridges are arranged, and capable of measuring a state within the well disposed at the outermost side, and including a shielding plate that moves to cover an opened upper portion of the well disposed at the outermost side to block introduction of light into the well.

The technology described herein generally relates to systems for extracting polynucleotides from multiple samples, particularly from biological samples, and additionally to systems that subsequently amplify and detect the extracted polynucleotides. The technology more particularly relates to microfluidic systems that carry out PCR on multiple samples of nucleotides of interest within microfluidic channels, and detect those nucleotides.

Described herein are systems, methods, and devices for pathogen identification. A system includes a housing configured to receive a sample comprising pathogen(s), a pipettor system disposed inside the housing, centrifuge(s) disposed inside the housing, a mechanical agitator disposed inside the housing, and a controller. The controller is configured to transfer the sample to a processing tube using the pipettor system, centrifuge the processing tube using the centrifuge(s) to concentrate the pathogen(s) in the sample, remove a fluid from the processing tube using the pipettor system, leaving the concentrated pathogens in the processing tube, add a lysis buffer to the processing tube using the pipettor system, move the processing tube to the mechanical agitator using the pipettor system, and agitate the processing tube using the mechanical agitator to perform lysis of the concentrated pathogens. The system is further configured to perform PCR using a nucleic acid extracted from the sample.

Dual channel sipper assemblies and related methods are disclosed. A reagent assembly for a sequencing platform includes a reagent cartridge having a first container including a container body and an open end. The container body defines a reagent chamber containing a liquid reagent. A cover is disposed over the open end and the cover includes a pressure and reagent port fluidly coupled to the reagent chamber. A sipper is adapted for piercing the cover of the reagent cartridge through the pressure and reagent port to both pressurize the reagent chamber and to aspirate liquid reagent from the reagent chamber. The sipper includes a first lumen and a second lumen. The first lumen is to deliver pressurized fluid to the reagent chamber. The second lumen is to aspirate liquid reagent from the reagent chamber.

The present invention relates to a method for qualitative analysis of a sample protein, which method comprises the steps of providing a water swollen gel column bed comprising bound protease and a sample protein in liquid buffer, digesting the sample protein into polypeptides by contact with the gel bed and subjecting the polypeptides to mass spectrometry (MS). The method is advantageously performed using back and forth flow of the sample protein including two or more repeats, and may be performed at a temperature of less than about 37 C., such as a temperature of less than about 30 C. The invention also includes an automated method as well as a device and a kit for performing mass-based analysis of proteins with higher speed than the prior art while maintaining conditions that are tolerable to the protease.
