Abstract: A centrifuge includes a regenerative braking safety system including an electrical system reversibly coupled to a power source. A motor is coupled to the electrical system. The motor is capable of driving a rotor using power delivered through the electrical system, and is further capable of supplying the electrical system with recovered energy. The recovered energy is electrical energy converted from kinetic energy of the rotor during regenerative braking of the motor. The safety system includes a power cut-off configured to disable the effect of regenerative braking of the motor when the electrical system is decoupled from the power source.
Abstract: Provided herein is a carryover-reducing liquid handling probe for an analytical system, incorporating a rigid sheath and a polymer core that extends from the sheath to act as the fluid contact surface.

Abstract: In a laser-based alignment system, a laser sensor tool, comprising a laser emitter and detector element can be gripped by a gripper unit of a robotic arm and used to automatically align the robotic arm with a work surface. A landmark on the work surface can be identified by scanning the work surface with the laser sensor in an X-Y plane. A center point of the landmark in the X-Y plane can be determined to align the gripper unit with the work surface in the X-Y plane. The robotic arm can be calibrated on a Z-axis by moving the gripper downward in a z-direction until the gripper unit contacts the work surface.

Abstract: Systems and methods for processing and analyzing samples are disclosed. The system may process samples, such as biological fluids, using assay cartridges which can be processed at different processing locations. In some cases, the system can be used for PCR processing. The different processing locations may include a preparation location where samples can be prepared and an analysis location where samples can be analyzed. To assist with the preparation of samples, the system may also include a number of processing stations which may include processing lanes. During the analysis of samples, in some cases, thermal cycler modules and an appropriate optical detection system can be used to detect the presence or absence of certain nucleic acid sequences in the samples. The system can be used to accurately and rapidly process samples.

Abstract: In flow cytometry, particles (2) can be distinguished between populations (8) by combining n-dimensional parameter data, which may be derived from signal data from a particle, to mathematically achieve numerical results representative of an alteration (48). An alteration may include a rotational alteration, a scaled alteration, or perhaps even a translational alteration. Alterations may enhance separation of data points which may provide real-time classification (49) of signal data corresponding to individual particles into one of at least two populations.

Abstract: The present invention discloses multi-purpose metering fluid/rinse reagents for use in automated cellular analyzers that use liquid volumetric metering. The compositions contain a chelating agent, an ionizing salt, optionally a stabilizing ion, a buffer, a non-hemolytic surfactant, and optionally an antimicrobial agent. Advantageously, the compositions produce less than one part-per-million of formaldehyde over the course of one year. Methods for using the compositions are also described.
Abstract: A system is disclosed. The system includes at least one image acquisition device configured to obtain one or more images of sample containers in a sample container holder. It also includes an image analysis device coupled to the at least one image acquisition device. The image analysis device is configured to analyze, by a processor, the one or more images of the sample containers in the sample container holder, to determine (a) a presence or absence of sample containers at sample container holder locations in the sample container holder, and (b) sample container characteristics of the sample containers in the sample container holder, wherein the sample container characteristics include one or more of cap color, cap shape, labels and markers associated with the sample containers, or one or more sample container holder characteristics.

Abstract: Methods and reagents are provided for determining the activation state of a signal transduction pathway signaling protein. There exists a need in the art for methods that can monitor the efficacy of a signal transduction inhibitor in a patient. Other needs exist for detecting and monitoring certain disease or disorders that are associated with aberrant activation of a signal transduction pathway signaling protein. The present assay provides a highly sensitive assay that is also useful in patient populations in which obtaining a large cellular sample is difficult, for example, neonates.

Abstract: Methods, reagents, kits and systems are disclosed for determining an analyte in a sample suspected of containing the analyte where all reagents are soluble in aqueous solution. One assay method includes treating a sample suspected of containing the analyte under conditions such that if the analyte is present, an activator is brought into reactive configuration with a chemiluminescent compound to activates it. The sample is also treated with an agent to reduce signal not related to analyte. Finally, the sample is treated with a trigger solution thereby producing light from the activated chemiluminescent compound. No reagents are associated with a surface or other solid phase.
